Note
This page contains release notes for versions 20.02.1.0 and newer.

Azul Zing Builds of OpenJDK (Zing) are available in two versions:

  1. Stream Builds: Fast-moving monthly releases (end of the month) that include all of the latest features and changes that are part of PSU releases. Free for development and evaluation. Use in production requires an active subscription.

    Current latest: 24.09.0.0

  2. Stable Builds: Builds that incorporate only CPUs, PSUs, and Azul Platform Prime critical fixes and do not uptake new features and non-critical enhancements from Stream Builds. Stable Builds are our primary vehicle for delivering time-sensitive bug-fixes to customers and are only available to Azul customers.

    Current latest: 24.08.101.0 and 24.02.500.0



Latest Stream Build

24.09.0.0

Release Notes PDF

Release date: October 3, 2024

This release is based on the Azul Zing Build of OpenJDK (Zing) 24.08.0.0 and corresponds to the following OpenJDK versions:

Major Version OpenJDK Version

8

1.8.0_422-b5

11

11.0.24+8-LTS

17

17.0.12+7-LTS

21

21.0.4+4-LTS

What’s New

  • Zing 24.09.0.0 increases the maximum code cache supported from 1758 MB to 4 GB. You can now set both ReservedCodeCacheSize and InitialCodeCacheSize to a value up to 4 GB.

  • In case you need to disable Extended Native Memory Tracking (NMT), Zing 24.09.0.0 includes new command line option UseExtendedNMT, which you can use to disable Zing’s Extended NMT, and EnableNMTIntegrityChecks, which you can use to disable checks on allocations. Zing runs in Extended NMT mode and includes integrity checks by default. Using -XX:-UseExtendedNMT tells Zing to run NMT in a Zulu-like mode. We do not recommend disabling Extended NMT except in very specific cases.

Known Issues

24.08.0.0

Release Notes PDF

Release date: August 30, 2024

This PSU release is based on the Azul Zing Build of OpenJDK (Zing) 24.07.0.0 and corresponds to the following OpenJDK versions:

Major Version OpenJDK Version

8

1.8.0_422-b5

11

11.0.24+8-LTS

17

17.0.12+7-LTS

21

21.0.4+4-LTS

What’s New

  • The command line option ProfileLogName has been deprecated and replaced with ProfileName. ProfileName supports all existing macros available for ProfileLogName. It is still possible to use ProfileLogName, however, we recommend that you update your configuration in order to guarantee that you have access to all of the latest features implemented in ProfileName.

    Note that using ProfileName overrides ProfileLogName, ProfileLogIn, and ProfileLogOut.

  • Zing 24.08.0.0 introduces a new feature to the Falcon compiler called Multi-Tiering. Multi-Tiering allows Falcon to schedule methods for compilation under different optimization levels, based on method hotness.

    Multi-Tiering assigns hot and active methods to final-tier compilation and cold or inactive methods to mid-tier compilation. Final-tier uses the default Falcon optimization level (usually Falcon optimization level 2) while Mid-tier uses Falcon optimization level 0.

    Enable Multi-Tiering using the command line option -XX:+UseMultiTiering.

    For more information on Multi-Tiering, see Analyzing and Tuning Warm-Up, Using Multiple Compiler Tiers

  • Zing 24.08.0.0 introduces the ability to apply ReadyNow transformations at runtime. This is done using the newly implemented command line options -XX:ApplyReadyNowTransformations or -XX:ApplyReadyNowTransformationsFile. You can specify which transformations are used on which generation of your ReadyNow profiles.

    A transformation profile can be stored on your machine in yaml format and called using -XX:ApplyReadyNowTransformationsFile=//path/to/file.yaml. or you can apply your transformation options directly in the parameters on the command line using -XX:ApplyReadyNowTransformations="\{transformations\:\[\{data: 0\}\]\}".

  • Zing 24.08.0.0 raises the maximum java heap size (Xmx) supported with non-ZST mode to 14000 GB (14 TB) on Intel Ice Lake and newer x86 processors when 5-level paging (LA57) is enabled at the OS level.

  • Zing 24.08.0.0 handles requests for PrintJNI without safepoint pause, allowing PrintJNI to run concurrently with your VM process.

  • July 2024 PSU release security fixes.

  • Zing 24.08.0.0 introduces a new parameter PrintGCHeadersGuaranteedIntervalSecs which can be used to specify a time interval for periodic output of headers in GC log. This helps open partial GC logs in GC log analyzer, for example those pulled from Splunk.

  • Zing 24.08.0.0 introduces Periodic NMT logging. With this feature, you can output NMT logs to the NMT output folder periodically. Since periodic NMT logging is a diagnostic feature, you must first unlock diagnostic VM Options using -XX:+UnlockDiagnosticVMOptions.

    To specify the output directory for NMT logs, use -XX:PrintNMTStatisticsRoot=<dir_name>. Setting this option enables periodic dumping.

    To specify the interval for printing the new report to the directory, use -XX:PrintNMTStatisticsAtIntervalSec=<interval in seconds>. The default value is 10 sec.

    Example settings for periodic NMT logging:

     
    java -XX:+UnlockDiagnosticVMOptions -XX:NativeMemoryTracking=summary -XX:PrintNMTStatisticsRoot=nmt -XX:PrintNMTStatisticsAtIntervalSec=20 Main

24.07.0.0

Release Notes PDF

Release date: July 31, 2024

This CPU release is based on the Azul Zing Build of OpenJDK (Zing) 24.06.0.0 and corresponds to the following OpenJDK versions:

Major Version OpenJDK Version

8

1.8.0_421-b3

11

17

17.0.11.0.101+3-LTS

21

21.0.3.0.101+4-LTS

What’s New

  • Zing 24.07.0.0 implements an intrinsification of the method java.lang.reflect.Array.get, leading to a significant performance improvement in some cases.

  • The logic around InlineTree has been greatly improved. This change allows the decisions reached by inlining to be reconstructed on request, instead of running through the tree with each query which sometimes leads to bloated recursive inlinings.

  • The MXBean PersistentProfileMXBean has been extended with getReadyNowTier1CompilesRate() and getReadyNowTier2CompilesRate(). These methods allow you to see what percentage of compiles are happening in ReadyNow, when compared to all compiles including non-ReadyNow.

  • July 2024 CPU release security fixes.

24.05.0.0

Release Notes PDF

Release date: May 31, 2024

This PSU release is based on the Azul Zing Build of OpenJDK (Zing) 24.04.0.0 and corresponds to the following OpenJDK versions:

Major Version OpenJDK Version

1.8.0_412-b4

11

11.0.23+9-LTS

17

17.0.11+9-LTS

21

21.0.3+9-LTS

What’s New

  • April 2024 PSU release security fixes.

  • The default value of -XX:ProfileStartupLimitInSeconds has changed from 60 to 0. This follows from a previous change where 0 was changed from "infinite" to actually 0 seconds. For more information on ProfileStartupLimitInSeconds, see Command Line Options, Advanced Miscellaneous Options.

  • Azul Zing 24.05.0.0 implements some behavioral changes to the command line option VMFootprintLevel. In order to reduce memory footprint, malloc arenas now use half the number of CPU cores when setting a non-default value of VMFootprintLevel; L, M, or S

  • The minimum value supported for Xms (initial heap size) was lowered drastically from 512 MB to 128 MB. Previously, the minimum supported Xms was 512 MB. The minimum supported Xmx (maximum heap size) remains unchanged at 512 MB. The purpose of this change is to reduce memory consumption from small utility processes which don’t require a high amount of memory.

    Note
    In case Xms and Xmx are set to the same value, while setting Xms somewhere between 128 MB and 512 MB, both values are rounded up to 512 MB in order to satisfy the minimum allowable Xmx.
  • Azul Zing 24.05.0.0 introduces a new command line option, -XX:ThpDisable, which can be used to disable Transparent Huge Pages (THP) in the entire JVM process, even when system THP settings are enabled. When -XX:+ThpDisable is set, THP is turned off, overriding the system default.

  • Azul Zing 24.05.0.0 is now able to collect Falcon diagnostics during OOM (Out of memory) errors.

  • Thread-local backoff for secondary_super_cache updates has been ported from OpenJDK, based on JDK-8316180 and is disabled by default. To enable this feature, use the option -XX:SecondarySuperMissBackoff=1000.

  • A new command line option, OptimizeIdentityHashForDistribution has been introduced in Zing 24.05.0.0. This option enables an alternate implementation for System.identityHashCode() which provides better distribution of objects at the cost of making the identity hash calculation itself slower. This option is disabled by default and can be enabled using -XX:+OptimizeIdentityHashForDistribution.

Known Issues

  • There are no new issues to report in this release.

21.0.2+13-LTS

What’s New

  • Zing 24.02.0.0 includes new options for defensive heap shrinking. Defensive heap shrinking dynamically reduces committed Java heap in order to avoid Out-of-memory (OOM) errors in container environments, which ordinarily lead to OOM kills and crashes.

    You can enable defensive heap shrinking using the flag -XX:+UseDefensiveHeapShrinking. See Command Line Options, Defensive Heap Shrinking for more information on tuning this option:

    Specifying VMFootprintLevel enables UseDefensiveHeapShrinking by default.

  • The C2 Compiler SeaOfNodesC2 has been deprecated in Zing 24.02.0.0. When you use the option -XX:+UseC2, the JVM uses KestrelC2 for C2 compilation.

  • The command line option UseOptimizedThreadLookup has been disabled by default due to its impact on virtual and physical memory consumption in some cases. This change can negatively effect the lookup times of threads such as with jmm_getThreadCpuTimeWithKind(). The optimization can be turned back on by default with -XX:+UseOptimizedThreadLookup.

  • Zing 24.02.0.0 implements a significant improvement to code cache segmentation. This improvement makes code cache segmentation elastic instead of fully committing the entire segment, greatly reducing the amount of wasted memory from code cache segmentation.

  • Following up from our previous deprecation of ZVision and ZVRobot components in Zing 23.08.0.0, we have now removed ZVision and ZVRobot components completely in Zing 24.02.0.0. This means that you are no longer able to use ZVision and ZVRobot with Zing. We recommend using Java Flight Recorder and Azul Mission Control for recording and viewing performance metrics for your JVM.

  • Zing 24.02.0.0 includes support for Optimizer Hub (formerly Cloud Native Compiler) on ARM64 system architecture.

  • The compilation ranking feature has been enabled again by default. Compilation ranking was disabled in Zing 23.08.201.0 due to performance issues in particular cases. If you are upgrading from a previous stream release, there is no change in behavior.

Known Issues

  • There are no new issues to report in this release.

24.01.0.0

Release Notes PDF

Release date: January 31, 2024

This release is based on Azul Platform Prime 23.12.0.0 and corresponds to the following OpenJDK versions:

Major Version OpenJDK Version

8

1.8.0_402-b3

11

11.0.22+7-LTS

17

17.0.10+7-LTS

21

21.0.2+13-MTS

What’s New

  • From Azul Platform Prime 24.01.0.0, the garbage collector’s (GC) CPU usage is logged by default. Previously, you had to use the option -XX+:PrintGCDetails. You can view these metrics now by default in GC Log Analyzer in the GC CPU Usage graph. GC CPU Usage is split into 3 metrics, "marking CPU usage," "relocation CPU usage," and "fixup pass," which appear as "New GC Mark," "New GC Reloc," and "New GC Fixup" in the GC CPU Usage graph.

  • Azul Platform Prime 24.01.0.0 includes a new lightweight, fully functional distribution of the Java Runtime Environment (JRE) for Java 8, 11, 17 and 21. The new Java JREs saves a significant amount of space by removing various debugging options and developer options. The Azul Platform Prime Builds of JRE still fully supports Optimizer Hub and Azul Vulnerability Detection (AVD).

  • Azul Platform Prime 24.01.0.0 introduces a small but significant change to the behavior of -XX:ProfileStartupLimitInSeconds. Now, when you set this option to 0, it means 0 seconds. Previously, if you set this flag to 0, it would be interpreted as "infinite". You can still specify "infinite" by using any negative number, for example -1. The default behavior without setting this option remains the same, i.e. the default remains 60.

  • January 2024 CPU and PSU release security fixes.

11

11.0.20.1+1-LTS

17

17.0.8.1+1-LTS

What’s New

  • Compilation ranks by priority, which allows the JVM to assign compilation ranks to methods, has been introduced to Azul Platform Prime 23.08.0.0. This allows the Falcon compiler to assign ranks, hot, warm, or cold, to methods in order to prioritize system resources to methods depending on their hotness. The value of compilation ranking is that compiler activity is optimized later in an application run, not only reducing system load and freeing up resources for the running application but also reducing application outliers.

    For more information on compilation ranks, see Analyzing and Tuning Warmup. For newly added options, see Command Line Options.

  • As of Azul Platform Prime 23.08.0.0, ZVision and ZVRobot components have been deprecated and are no longer actively developed. While we still support these components, we encourage users to switch to Java Flight Recorder, as ZVision and ZVRobot are planned for End-of-Life with Azul Platform Prime 24.02.0.0.

  • Support for the latest features in Optimizer Hub (formerly Cloud Native Compiler) 1.8.0. As Cloud Native Compiler expands its scope to offer more functionality than just offloading compilations, it is time to rebrand the offering to better reflect what it does. Starting with release 1.8, we are using the following naming:

    • Optimizer Hub (was Cloud Native Compiler) - The name of the overall component that you install on your Kubernetes cluster.

    • Cloud Native Compiler (was Compiler Service) - The feature that performs the compilation on Optimizer Hub.

    • ReadyNow Orchestrator (was Profile Log Service) - The feature that records and serves ReadyNow profiles to JVMs.

  • In Optimizer Hub 1.8, all major artifacts and command line switches use the updated branding. This includes, but is not limited to:

    If you are using release 1.7 and earlier, all of the previous spellings of artifacts still work. Additionally, all of the pre-1.8 command-line arguments will continue to work for a period of one year from the release of 1.8.

  • The command line option PreferContainerQuotaForVMInternalCPUCount has been set to true by default in order to make calculations of internal thread counts, as well as budgeting options, more clear in container environments.

    In container environments where both CPU shares and CPU quota are specified, such as with Kubernetes where these are commonly specified, the VM now uses quota to calculate compiler and GC thread counts. Prior to Azul Platform Prime 23.08, it was using half of quota for the calculation.

What’s New

  • ZVision and ZVRobot have been separated from the Azul Platform Prime package due to a known vulnerability in jQuery 1.4.3, which is used in building the ZVision and ZVRobot utilities. At this time, Azul is not aware of any vulnerability in ZVision itself. For this reason, ZVision is still available for download for Azul Platform Prime subscribers at https://ftp.azul.com/releases/Zing/ZVision/ZVTools.zip

  • The command line option -XX:CompileCommand has been updated to use FalconCompileThreshold.

    This option is used in the following way:

  • A new option, C2CompileThreshold, has been added. This option allows the C2 compile threshold to be specified for individual methods. This option was introduced because some methods that are rarely called are still important and need to undergo regular optimization. This is set using -XX:CompileCommand in the following way:

    -XX:CompileCommand="option,<Class>::<method>,C2CompileThreshold=<threshold>"

  • The maximum supported code cache size has been increased to 1758 MB when AllocCodeCacheInLower2G is disabled using -XX:-AllocCodeCacheInLower2G.

  • It is no longer necessary to LD_PRELOAD the libnmt_hooks.so library in order to use extended Native Memory Tracking (NMT). The libnmt_hooks.so library is now linked by default.

  • Using Java Flight Recorder, you can now see exact JIT name for each stacktrace frame in Azul Mission Control in the Method Profiling tab. This uses the option JFRDistinguishJITTypes, which is set to true by default, and shows either C1, C2, or Falcon for each stacktrace frame. With JFRDistinguishJITTypes set to false, it shows JIT compiled.

Known Issues

  • There are no new issues to report in this release.

  • Cloud Native Compiler (CNC) 1.7 client support.

  • The command line option, AllocCodeCacheInLower2G, is now supported on the AArch64 system architecture, which is set to true by default. This option allocates code cache and related data structures at virtual address within 2 GB. To allow allocation to higher memory addresses, use -XX:-AllocCodeCacheinLower2G.

  • A new command line option, GPGCCommitInitialHeapLazily, has been introduced, which is set to false by default. When enabled, this option prevents the whole of the initial heap size, InitialHeapSize or -Xms, from being committed from the OS upfront.

    With this option enabled, use the option GPGCLazyInitialHeapCommitPercent to specify how much of Xms shall be committed from the OS upfront, at startup. The default value for GPGCLazyInitialHeapCommitPercent is 50. The remainder gets committed based on regular elastic heap heuristics.

  • The command line option InitialHeapSize is now incorporated in Azul Platform Prime in order to keep compatibility with OpenJDK. InitialHeapSize can be used instead of -Xms<size> on the command line.

Note
The command line argument MaxHeapSize can also be used instead of -Xmx<size>

What’s New

  • Zing 23.02.0.0 contains the General Availability (GA) release of Azul Prime Builds of OpenJDK 19 for x86_64 systems.

  • Cloud Native Compiler (CNC) 1.6.1 client support.

  • NativeMemoryTracking has been extended with further Falcon tracking support.

    To enable "extended tracking," set LD_PRELOAD=$JAVA_HOME/etc/zing/lib/libnmt_hooks.so in addition to regular NMT flags which are described in Native Memory Tracking Options and in the Oracle documentation.

  • Zing 23.02.0.0 introduces new CPU budgeting features for the Falcon Tier 2 compiler. CPU Budgeting tells the Tier 2 compiler when to run and how many CPU threads to use, pre and post warmup.

    With these new features, it is possible to specify allocated threads as a percent, meaning the compiler and the running application can share resources, resulting in less pauses and more stability for the running application. Previously, only whole numbers of threads could be allocated.

    To enable these new features, use the argument -XX:+EnableTier2CompilerBudgeting.

    New Falcon CPU Budgeting features are listed in Command Line Options, CPU Budgeting Options

  • A new command line option, AllocCodeCacheInLower2G has been introduced and is set to true by default. This option allocates code cache and related data structures at virtual address within 2 GB. To allow allocation to higher memory addresses, use -XX:-AllocCodeCacheinLower2G. This option is only available for x86_64 systems.

  • Lower GC pauses with JVMTI - JVMTI tag map clearing has been moved outside of safepoint pause by default. This is set by the command line argument ConcurrentJVMTITagMapClearing and is set to true by default.

  • Falcon improvement - Register allocation enhancement that improves code generation for derived pointers around GC safepoints. This allows derived pointers to rematerialize immediately before their use instead of after every safepoint. This is beneficial when a pointer is live across many statepoints but has few uses.

  • Allocation publication barrier optimizations for AArch64 in Falcon. Testing has yielded up to an 8.5% performance improvement from this optimization.

  • The output format for -Xlog:safepoint has been changed to match OpenJDK for JDK13 and above.

What’s New

  • January 2023 CPU and PSU release security fixes.

  • Cloud Native Compiler (CNC) 1.6 client support.

  • You can now read and write ReadyNow profile logs to Cloud Native Compiler. This simplifies getting ReadyNow profile logs in and out of containers and other environments without persistent storage.

  • Compile stashing has been disabled by default, even when using ReadyNow.

    Existing ReadyNow users that want to maintain the same compile stashing behavior as in earlier releases should ensure the -XX:+FalconUseCompileStashing flag is set.

    Users who wish to use compile stashing with the new Profile Log Service must ensure both +FalconUseCompileStashing and +CNCEnableRemoteCompiler flags are set.

  • FalconContextReset is now set using ergonomics heuristic based on the number of Falcon compiler threads, unless specified explicitly. Falcon compiler threads reset the internal caches after every FalconContextReset number of compilations. This is a tradeoff between compilation speed and memory consumption. The more often the caches are reset, the less memory is consumed but more time is spent rebuilding the caches.

    Currently, the value of FalconContextReset is chosen as FalconContextResetFactor=<number of Falcon threads> nested between FalconContextResetLowerLimit and FalconContextResetUpperLimit.

What’s New

  • Zing 22.12.0.0, through various changed and updates, has been able to achieve 10% lower GC CPU usage on Cassandra.

  • Zing 22.12.0.0 lowers the amount of GC pauses with hidden classes.

  • Falcon has been improved for Jackson as well as other optimizations to the Falcon JIT compiler.

  • New JMX MXBean metrics replace old metric name below java.lang.GarbageCollector to increase accuracy for GC monitoring added with JDK-8265136: Previously, metric "GPGC New/Old" was providing a sum of GC pauses and concurrent GC duration. This metric is replaced by the following:

    • GPGC New/Old Cycles: duration time in ms of the concurrent GC which runs in parallel to application threads and is not stopping the application.

    • GPGC New/Old Pauses: GC pause time in ms.

On Java 11 and 17, the new metrics are enabled by default and the old removed. If you need to switch back to the old metric, add -XX:+GPGCReportLegacyGarbageCollectorMXBean.

On Java 8, only the old metric is active by default. To switch to the new metric add -XX:-GPGCReportLegacyGarbageCollectorMXBean.

22.10.0.0

Release Notes PDF

Release date: October 31, 2022

This CPU/PSU release is based on Azul Platform Prime 22.09.0.0 and corresponds to the following OpenJDK versions:

Major Version OpenJDK Version

8

8u352-b08

11

11.0.17+8

13

13.0.13+5

15

15.0.9+5

17

17.0.5+8

What’s New

  • October 2022 CPU and PSU release security fixes

  • Compatibility with Cloud Native Compiler (CNC) version 1.5

  • Support for the GA release of Azul Vulnerability Detection (AVD).

  • Changes for containers regarding thread pool size calculation and number of available CPUs.

    With the October 2022 release of Java 11 and 17, the default calculation of available CPU cores will change, following JDK-8281181. Previously, the number of available CPU cores was in some situations calculated based on the lower bound defined in the environment. With the change in this release, the lower bound won’t be used anymore and the calculation will only be based on the upper limit of the environment. If in container-based systems no upper limit is defined, the total number of CPUs on the host machine is read as upper limit.

    A situation where a change will occur is, for example, a Kubernetes container where neither CPU requests nor CPU Limits are set, as previously the JVM would select only 1 CPU core as available in this situation while after the chance, it will select all available CPU cores of the environment which can lead to higher resource usage as thread pools of various open source frameworks are using this calculation for sizing. To verify if your systems are effect, check especially those where no upper limit is defined.

    In case you need to switch back to the previous calculation, add -XX:+UseContainerCpuShares to the Java command line.

    Other terms used in the context of CPU definitions are for lower bound "CPU Requests" or "cgroups cpu.shares", and for upper limit "CPU Limits" or "cgroups cpu.cfs_quota_us".

    When both quota and shares are specified for a cgroup and UseContainerCpuShares is true, the number of GC and compiler threads are derived based on a total processor count calculated as (quota+shares)/2. When UseContainerCpuShares is false the number is derived based on a total processor count calculated as (quota/2).

    To check the current setting, for example, to compare previous and current Java versions in your environment, use the following example to display the actual number of CPUs as seen by application code and run it inside your container environment:

    File AvailableCPUs.java:

     
    public class AvailableCPUs { public static void main(String[] args) { System.out.println("CPUs: " + Runtime.getRuntime().availableProcessors()); } }

    To run it:

     
    java -showversion AvailableCPUs.java

Known Issues

  • There are no new issues to report in this release.

Resolved Issues

  • ZVM-25268 - As a part of the PSU update, UseContainerCpuShares has been set to false (off) by default.

  • ZVM-22642 - The GC log now reports data from remote compilations which can be viewed in GC Log Analyzer.

What’s New

  • Includes all October 2021 CVE fixes.

  • Azul Platform Prime 21.10.0.0 contains the October 2021 CPU release of OpenJDK. Azul Platform Prime 21.10.0.0 brings the associated JDK 7, JDK 8, JDK 11, JDK 13, and JDK 15 versions to October 2021 CPU security update levels.

  • The peak heap occupancy target, used by heuristics to decide when to trigger a garbage collection, is now managed dynamically by default. The dynamic changes can be disabled by setting GPGCTargetPeakHeapOccupancyPercent to a desired value.

  • Increased parallelism between collectors for the new generation and old generation. Helps reduce the peak duration for a new generation collection and reduce allocation delays during peak load.

  • The number of concurrent GC threads is now changed dynamically when -Xms is set to the same value as -Xmx, or when Azul Zing System Tools (ZST) is installed. At JVM start a low number of concurrent GC threads is employed. If later during application uptime the GC Time Percent metric increases beyond a threshold, more GC threads are added to reduce the number of GC cycles. The limit for the total number of GC threads is 3/4 of the process' available CPU threads. As of this Prime version, the number of threads will never shrink later.

    To disable the dynamic handling, use the following on the command line: -XX:-UseDynamicNumberOfGCThreads

    If one of the following flags is set on the command line, the dynamic handling will also be disabled:

    • -XX:GPGCThreads=N

    • -XX:GenPauselessNewThreads=N

    • -XX:GenPauselessOldThreads=N

  • General performance improvements.

  • More intrinsics from Java 17.

Resolved Issues

Issue ID Description

ZVM-xxxx

High CPU utilization by HeapCommit thread in some specific scenarios. This only applies when -Xms isn’t set or set to less than -Xmx.

  • Various performance improvements with Falcon compiler:

    • Fixed extra spills causing performance penalties by supporting live gc values on registers for calls which can throw exceptions

    • Improved performance of applications that frequently use Unsafe.allocateInstance.

    • Implemented nested locks elimination optimization for multiple nested locks on a given object under the condition that the nested lock state is not inspected.

Resolved Issues

ZVM-19972

JVM memory metrics like Runtime.getRuntime.totalMemory() and Runtime.getRuntime.maxMemory() and related like java.lang.management.MemoryMXBean now include JVM-internal memory usage and will show a few MBytes larger numbers now. Calculations and methods around free memory calculation are not affected and will return the same results as before. That means for example Runtime.getRuntime.freeMemory() or difference calculation between attributes like "used" and "total" memory will also result in the same as in previous releases.

15.0.3+3

What’s New

  • Non-ZST Heap Elasticity introduced. See Recommended Heap Size for details. When heap elasticity is enabled, the Garbage Collector tries to minimize the memory footprint, keeping it between the user- defined range of -Xms and -Xmx. At the same time, the CPU usage of the Garbage Collector is monitored and the memory minimizing goal relaxed in case the CPU usage increases too much. Heap Elasticity is not available when Azul Zing System Tools (ZST) is installed.

  • Azul Platform Prime 21.05.0.0 makes the OpenJDK C1 OSR the default OSR for the Falcon compiler. The C1 OSR takes much less time and CPU resources to fully optimize your code to steady-state performance.

  • Stream Builds (previously known as Feature Releases) are now free for use in development and evaluation. As such, the builds no longer check for an evaluation license.

  • Latency improvement for applications with frequent Unsafe.get() and put() calls.

  • Fixed heap dump compatibility issue that prevented opening Zing head dumps in IntelliJIdea.

  • Enabled jcmd ManagementAgent command option support.

Major Version OpenJDK Version

7

7u292

8

8u282

11

11.0.10+9

13

13.0.6+5

What’s New

  • C2 Improvement

    The default JIT compiler on Zing JDK 8 and JDK 7 is changed from SeaOfNodesC2 to KestrelC2 when Zing C2 mode is enabled with -XX:+UseC2.

    For Zing JDK 11, this improvement was made in Zing 20.04.0.0.

    KestrelC2 is a C2 implementation introduced to Zing in 2020. It is based on a lightweight use of the LLVM backend and typically produces faster code than UseSeaOfNodesC2 while keeping compilation effort at similar levels. UseKestrelC2 generally exhibits a significantly lower compilation-time CPU consumption compared to Falcon.

    See Using Zing Command-Line Options for -XX:[+/-]UseKestrelC2 and -XX:[+/-]UseSeaOfNodesC2 command-line options and details.

    The default JIT compiler in Zing is the high-performance Falcon introduced in 2017.

  • New Experimental Features

    Zing 21.01.0.0 includes optional experimental support for interaction with connected runtime services through an emerging protocol in Zing 11 and Zing 8.

    These experimental capabilities are enabled by the -XX:+UseCRS command-line option and turned off by default. Being an experimental Zing option, it must be unlocked by preceding -XX:+UnlockExperimentalVMOptions.

  • Performance Improvement

    Zing 21.01.0.0 introduces an improved escape analysis for arrays in the Falcon compiler.

    The improvement includes an optimization for array reallocation pattern (e.g., java.util.Arrays.copyOf) to avoid redundant copying. Notably, this optimization improves the performance of string concatenation using the StringBuilder class by the elimination of excessive reallocations of the underlying StringBuilder buffer.

  • Support for EdDSA Signature Algorithm

    Zing 21.01.0.0 introduces the OpenEdDSA provider which can be used for cryptographic signatures using the Edwards-Curve Digital Signature Algorithm (EdDSA) in Zing 8 with no application or code changes. See JEP 339: Edwards-Curve Digital Signature Algorithm (EdDSA) for details.

    The OpenEdDSA public API is provided in the org.openeddsa.java.security.interfaces and org.openeddsa.java.security.spec packages.

    To enable the OpenEdDSA provider, do either of the following:

    • configure the Java Runtime Environment for the OpenEdDSA provider by adding the entry below to the $JAVA_HOME/jre/lib/security/java.security file

       
      security.provider.10=org.openeddsa.security.OpenEdDSA
    • add the OpenEdDSA provider directly to your code

       
      // Add OpenEdDSA provider java.security.Security.addProvider(new org.openeddsa.security.OpenEdDSA());

11.0.7+10

What’s New

  • The release of Zing 20.04.0.0 contains April 2020 critical patch update (CPU) security and critical bug fixes and brings the associated JDK 7, JDK 8, and JDK 11 versions to April 2020 CPU security update levels.

  • Zing 20.04.0.0 incorporates additional non-security changes associated with the April PSU 2020 OpenJDK 8u252 and OpenJDK 11.0.7 release contents.

  • Starting with Zing 20.04.0.0, the -XX:+UseC2 option can use one of two separate implementations of C2 JIT compilation: a traditional UseSeaOfNodesC2 mode and a new UseKestrelC2 mode.

  • The new mode is selected with +UseKestrelC2 which is on by default for Zing 11 and off by default for Zing 8 and Zing 7. This mode enables a C2 implementation introduced to Zing in 2020. It is based on a lightweight use of the LLVM backend and typically produces faster code than UseSeaOfNodesC2 while keeping compilation effort at similar levels. UseKestrelC2 generally exhibits a significantly lower compilation-time CPU consumption compared to Falcon.

    The old mode is selected with +UseSeaOfNodesC2 which is off by default in Zing 11 and on by default for Zing 8 and Zing 7.

    See Using Zing Command-Line Options for UseKestrelC2 and UseSeaOfNodesC2 command-line options and details.

  • Zing 20.04.0.0 introduces a compilation time improvement.

  • The release of Zing 20.04.0.0 introduces an increased maximum Java heap size from 1 TB to 2.5 TB in the default non-ZST mode.

    The maximum Java heap size for the Zing Virtual Machine with ZST is 20 TB.

  • In Zing 20.04.0.0, a new Java Flight Recorder functionality allows you to collect profiling data about applications that use JNI invocations.

  • The release of Zing 20.04.0.0 includes optimizations targeted at reducing JNI transition costs. The cost of a native call from Java was reduced, and the implementation of the accessor functions used to retrieve fields of Java objects from native code was also improved. Most applications will not be affected, but applications with many native transitions (such as a socket or file IO) may see the marked improvement.

    See Using Zing Command-Line Options for UseFastJNIAccessors, UseMembar, and UseThreadStateNativeWrapperProtocol command-line options and details.

  • Zing 20.04.0.0 excludes debug symbols embedded in libjvm.so, which reduces the filesystem footprint of a Zing installation by 280 MB.

24.08.1.0

Release Notes PDF

Release date: September 20, 2024

This release is based on the Azul Zing Build of OpenJDK (Zing) 24.08.0.0 and corresponds to the following OpenJDK versions:

Major Version OpenJDK Version

8

1.8.0_422-b1

11

11.0.24+8-LTS

17

17.0.12+7-LTS

21

21.0.4+4-LTS

What’s New

  • Zing 24.08.1.0 includes a performance improvement in ReadyNow which improves the efficiency and reporting of the built-in class loader identification task.

  • In case you need to disable Extended Native Memory Tracking (NMT), Zing 24.08.1.0 includes new command line option UseExtendedNMT , which you can use to disable Zing’s Extended NMT, and EnableNMTIntegrityChecks , which you can use to disable checks on allocations. Zing runs in Extended NMT mode and includes integrity checks by default. Using -XX:-UseExtendedNMT tells Zing to run NMT in a Zulu-like mode. We do not recommend disabling Extended NMT except in very specific cases.

  • Zing 24.08.1.0 features an update to JVMTI behavior in order to bring it to the modern standard. Previously, a few commercial Java application performance monitoring tools have been reporting too long GC pause times because Zing was reporting non-pausing concurrent GC durations wrongly as GC pauses over JVMTI events JVMTI_EVENT_GARBAGE_COLLECTION_START (GarbageCollectionStart) and JVMTI_EVENT_GARBAGE_COLLECTION_FINISH (GarbageCollectionFinish).

    The new correct reporting may increase the actual GC pauses slightly if monitoring software attached with -javaagent using JVMTI is active. By adding -XX:-GPGCNotifyJVMTIGCEventsInSafepoint the reporting of GC events can be moved outside the pause.

Known Issues

  • There are no new issues to report in this release.

24.02.401.0

Release Notes PDF

Release date: October 3, 2024

This release is based on Azul Platform Prime 24.02.400.0 and corresponds to the following OpenJDK versions:

Major Version OpenJDK Version

11

11.0.24+8-LTS

17

17.0.12+7-LTS

21

21.0.4+4-LTS

What’s New

  • Azul Zing 24.02.401.0 improves the efficiency and reporting of the builtin class loader identification task, ensuring that the builtin class loader identification tasks finish within an expected timeframe.

  • Azul Zing 24.02.401.0 adds a mode which makes ReadyNow file tasks through the request buffer rather than directly to the compile queue. This change can reduce overhead in some cases.

  • In case you need to disable Extended Native Memory Tracking (NMT), Zing 24.02.401.0 includes new command line option UseExtendedNMT, which you can use to disable Zing’s Extended NMT, and EnableNMTIntegrityChecks, which you can use to disable checks on allocations. Zing runs in Extended NMT mode and includes integrity checks by default. Using -XX:-UseExtendedNMT tells Zing to run NMT in a Zulu-like mode. We do not recommend disabling Extended NMT except in very specific cases.

24.02.302.0

Release Notes PDF

Release date: July 17, 2024

This PSU release is based on Azul Platform Prime 24.02.301.0 and corresponds to the following OpenJDK versions:

Major Version OpenJDK Version

8

1.8.0_421-b2

11

11.0.23.0.101+2-LTS

17

17.0.11.0.101+3-LTS

21

21.0.3.0.101+4-LTS

What’s New

  • Zing 24.02.302.0 is able to track detailed ReadyNow task execution. This tracks data on the amount of time tasks are waiting in the compiler queue and actual work done, and compiles those total values into a histogram.

  • Zing 24.02.302.0 implements an intrinsification of the method java.lang.reflect.Array.get, leading to a significant performance improvement in some cases.

  • You can now use more patterns in the DumpIR compile command to specify multiple DumpIRToDiskOf options, allowing you to collect the IR dump for multiple different compilations without using a wide pattern which can potentially lead to overflow of storage.

Known Issues

  • There are no new issues to report in this release.

What’s New

  • Internal bug fixes.

  • The starting point of the time period specified by the option CompilerWarmupPeriodSeconds has been updated. Previously, this time period began at the execution of the Main method. But, since pre-Main can have unexpectedly long initializations, the ending point of this time period could become unpredictable. The starting point of this time period has been changed to JVM startup in order to include pre-Main, giving much better predictability of when this time period ends.

Known Issues

23.02.401.0

Release Notes PDF

Release date: October 12, 2023

This release is based on Azul Platform Prime 23.02.302.0 and corresponds to the following OpenJDK versions:

Major Version OpenJDK Version

8

1.8.0_382-b2

11

11.0.20.1+1-LTS

17

17.0.8.1+1-LTS

What’s New

  • The starting point of the time period specified by the option CompilerWarmupPeriodSeconds has been updated. Previously, this time period began at the execution of the Main method. But, since pre-Main can have unexpectedly long initializations, the ending point of this time period could become unpredictable. The starting point of this time period has been changed to JVM startup in order to include pre-Main, giving much better predictability of when this time period ends.

Known Issues

  • There are no new issues to report in this release.

What’s New

  • ZVision and ZVRobot have been separated from the Azul Platform Prime package due to a known vulnerability in jQuery 1.4.3, which is used in building the ZVision and ZVRobot utilities. At this time, Azul is not aware of any vulnerability in ZVision itself. For this reason, ZVision is still available for download for Azul Platform Prime subscribers at https://ftp.azul.com/releases/Zing/ZVision/ZVTools.zip

  • It is no longer necessary to LD_PRELOAD the libnmt_hooks.so library in order to use extended Native Memory Tracking (NMT). The libnmt_hooks.so library is now linked by default.

  • July 2023 CPU and PSU release security fixes.

What’s New

  • Internal bug fixes.

  • Backport issue ZULU-39745 - Support custom security providers in Azul Zing builds of JDK17.

    The Java launcher can be updated to easily configure and enable custom security providers:

    1. Add a new java launcher option:

      --custom-providers=<custom_provider_name>(,<custom_provider_name>)

    2. Zing JDK will read custom provider configuration from the file located in the $JAVA_HOME/conf/<custom_provider_name>.properties

      Example of the configuration file:

       
      # Add name custom provider jar --module-path=<custom_provider_jar> # The following properties are required to access JDK internal classes from the custom provider --add-exports=java.base/<package>=<custom_provider_module_name> --add-opens=java.base/<package>=<custom_provider_module_name> # The following option allows to access classes from non-modular 3rd party libraries --add-reads=<custom_provider_module_name>=ALL-UNNAMED # The following option reads custom security properties -Djava.security.properties=<security_property_file>

      Zing JDK will read <custom_provider_jar> and <security_property_file> from the $JAVA_HOME/conf/<custom_provider_name> directory.

What’s New

  • Internal bug fixes.

  • October 2022 PSU release security fixes

  • Important information regarding Java in containers (Docker, Kubernetes, and related) about automatic thread pool size calculation and number of CPUs available to the application:

    While in the general October 2022 release of Java 11 and 17, the default calculation of available CPU cores has changed in container environments following JDK-8281181, this change wasn’t made in the Azul Platform Prime stable release 22.08.200.0 to allow seamless transition from previous stable versions.

    That means, Azul Platform Prime 22.08 differs in this aspect from current OpenJDK. In practical use, this difference will only affect those situations where a new migration from OpenJDK to Prime 22.08 is started. If you notice your application performance being affected during such a transition from OpenJDK to Prime 22.08 add -XX:-UseContainerCpuShares to the Java command line to switch Azul Platform Prime to the same new calculation method as OpenJDK.

    To check your environment in general about this change, independent of whether it is running on OpenJDK or Azul Platform Prime, run the following command inside your container to display the actual result of the available CPU number calculation:

    Save the following code to file AvailableCPUs.java:

     
    public class AvailableCPUs { public static void main(String[] args) { System.out.println("CPUs: " + Runtime.getRuntime().availableProcessors()); } }

    Run it:

     
    java -showversion AvailableCPUs.java
