12629 |
18.01.0.0 |
The application threads waits to be notified by the collector until the end of next new collection for allocations when they hit allocation failure. The use of the newly introduced -XX:GPGCMutatorSleepBeforeAllocRetryMS option makes the delayed to respond to the freed pages earlier and helps in reducing the length of allocation delays seen by the application threads. |
12428 |
17.12.1.0 |

12492 |
17.11.1.0 |
Interpreter or other runtime ZVM abort following a deoptimization of Falcon compiled code and an attempt to recompile and run the newly compiled method. Internal root cause is Falcon compiler’s reuse of OopTable indices. |
8341 |
17.11.0.0 |
ZVM will not start if -Xmx and -Xms are both specified and have values that are odd numbers. |
11143 |

17.06.0.0 |
INVOKEINTERFACE called on the java.lang.Object method in ASM-generated byte code fails after several iterations. |
10428 |

9463 |
16.12.3.0 |
Frequent New GC cycles can lead to Java heap live set growth. When the New GC intercycle time is lower than the promotion threshold, objects can be retained in the new generation causing a growth in the live set. This affects ZVM versions 15.09.0.0 through ZVM 16.12.2. |
7911 |
16.12.2.0 |
Crash with the following problematic frame: C [libjvm.so+0x38d1c2] jvmti_GetTime+0x62. |
9050 |
16.12.2.0 |
On some RHEL 5 systems, where the command: find /sys/devices/system/cpu -name thread_siblings produces a list of files that is in descending numerical order by a CPU directory name, ThreadOpt will exit with an IndexOutOfBoundsException. |
9086 |
16.12.1.0 |
Applications can hang when ZVM runs with the Falcon compiler. |
8655 |

No timestamp generated with the +PrintGCDetails option alone on command line causes gcLogAnalyser "unable to read". |
8561 |
16.10.1.0 |
ZVM can exit due to code cache exhaustion by Java monitors. Applications which make heavy use of Java monitors either due to lock contention or wait/notify mechanisms, can potentially see a high footprint related to monitors in the code cache. |
8224 |
16.10.0.0 |
A stray C2 thread is running at 100% CPU without making any forward progress. |
8071 |
16.07.1.0 |
C-Heap Leak happens in raw-monitor creation. RawMonitors are leaking semaphore objects which are eagerly created during VMLock creation. The fix includes releasing sem_t objects and calling sem_destroy. |
7756 |
16.07.1.0 |
ZVM crashes with the following problematic frame: [libjvm.so+0x318ab3] java_lang_Class::as_klassOop(oopDesc*)+0x23. |
2820 |
16.07.1.0 |
Nashorn benchmark stalls after encountering data error processing profile log error (error: 101) while running Nashorn benchmarks with ReadyNow enabled. The fix adds supports for dealing with Nashorn and eliminates this issue. |
4758 |
16.07.0.0 |
Additional control flags introduced to prevent startup crashes due to usage of ProfileLogIn. Following are those control flags: * ProfileUsePersistedInstructionData * ProfileProactivelyCompileC1 * ProfileProactivelyCompileC2 |
4811 |
16.07.0.0 |
jstat -profile (and -profileerrors) returned unresolved symbols when ProfileLogIn is not specified. The fix now ensures that zeros will be printed instead of unresolved symbols. |
5803 |
16.07.0.0 |
Wrong class was being loaded only when using the ProfileLogIn profile. The fix implements safe mode for ReadyNow to avoid an improper speculative load that might produce a misleading and worrisome report. |
6300 |
16.07.0.0 |
Removed non-relevant data from graphs (Old Gen Collector: App Threads Delay and Pages Promoted). |
6778 |
16.07.0.0 |
ReadyNow failed to recognize the generated Lambda classes as generated. The fix implements safe mode for ReadyNow to use when ReadyNow’s generated class heuristics do not work for a class generator. |
7422 |
16.07.0.0 |
Enabling ProfileLiveObjects seems to increase GC cycle durations significantly. The fix implements an improved hash function along with few other optimizations resulting in reduced GC cycle durations. |
7434 |
16.07.0.0 |
The default value of MlockLevel has been changed to 1 from 0: * MlockLevel=0 – do not attempt any mlocks * MLockLevel=1 – quietly attempt to mlock libjvm.so |
7451 |
16.07.0.0 |
Crash with the following problematic frame: StubRoutines::find_SEGV_continuation_address. |
7654 |
16.07.0.0, 16.01.7.0 |
Resolving an orphaned FinalLive objects through JNI weak handle during ConcurrentRefProcessing could lead to the following crash: guarantee(loop_count < size) failed: should have found the relocation record |
7422 |
16.01.7.0 |
Enabling ProfileLiveObjects seems to increase GC cycle durations significantly. The fix implements an improved hash function along with few other optimizations resulting in reduced GC cycle durations. |
5547 |
16.01.7.0 |
When running on some Cassandrs nodes, the following enexpected error has been detected: guarantee(GPGC_Marks::is_any_marked_strong_live(obj)) failed: NewGen oop at final clear not strong live |
6907 |
16.01.6.0 |
aCrash due to an internal error: guarantee(loop_count < size) failed: should have found the relocation record The fix ensures that a class of a Java object is treated as StrongLive even if that object is itself only FinalLive. This guarantees that the classes of FinalLive objects cannot be orphaned before the StrongLive mark-through of FinalLive referents, and will ensure their relocation. |
6058, 6108 |
16.01.5.0 |
High GC pauses due to JVM code being paged out. The fix introduces a new command-line option MlockLevel, which can be tuned. If the flag is set without a value, the default ensures no page JVM code page-outs. The option specifies one of four mlock strategies: . Do not attempt any mlock (EARLY) . mlock libjvm.so text region (LATE) . mlockall (EARLY) . mlockall (LATE) Example: use -XX:+MlockLevel=1001 to attempt strategy 1 while reporting verbosely. This option should be used only with guidance of Azul Support. |
6258 |
16.01.5.0 |
A random error code is being returned from the JDK method: java.util.prefs.FileSystemPreferences.lockFile0(). |
6436 |
16.01.5.0 |
In ZVision, clicking on the tty_lock entry in zvision → threads → contention causes a crash. |
6631 |
16.01.5.0 |
+MinimizeJNICriticalLock causes an IllegalArgumentException in java.util.zip.Deflater.deflate. |
6898 |
16.01.5.0 |
Nginx-Clojure does not work with Zing because the linker option -Wl,-soname,libjvm.so has not been passed and the libjvm.so library cannot be found. |
7071 |
16.01.5.0 |
Zing VM can crash at very early stages due to lack of system resources. |
6542 |
16.01.3.0 |
Applications that use large chunks(>100s of MBs) of DirectByteBuffer could potentially face high TTSP times in New/OldGC pause3 because of the deallocation of these buffers. |
6791 |
16.01.3.0 |
NullPointerException caused by wrong code generated from C2. |
6938 |
16.01.3.0 |
Thread.sleep can sleep ~30% longer than specified when the Intel pstate driver is enabled. The pstate driver can be disabled to workaround this problem with older ZVMs. You can determine whether the pstate driver has been enabled by checking /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver for the string “intel_pstate”. |
6956 |
16.01.3.0 |
A race condition in CodeCache::GPGC_unlink can cause a crash when there are multiple GenPauselessOldThreads. This affects ZVM versions 16.01.0.0, 16.01.1.0, and 16.01.2.0. For these ZVMs, the workaround is to set -XX:GenPauselessOldThreads=1 but this can cause a spike in Old GC cycle times for applications with a large live set. |
6736 |
16.01.2.0 |
Fatal error in native method: JDWP PushLocalFrame: Unable to push JNI frame, jvmtiError=AGENT_ERROR_OUT_OF_MEMORY(188). |
