What’s New
-
On arm64, the Zing
.debpackage installed to/opt/zing. It now installs to/usr/lib/jvm, matching amd64 and the Debian JVM convention.
-
Three Multi-Tiering command-line options are now product options. Setting them no longer requires
-XX:+UnlockExperimentalVMOptions.Command-Line Option Description Default -XX:MultiTieringSamplingIntervalMS=<value in milliseconds>60000
-XX:MultiTieringSamplingStartDelayMS=<value in milliseconds>The delay before Multi-Tiering starts sampling. Increase this to skip the early startup window.
0
-XX:FalconMidTierOptimizationLevel=<level>The Falcon optimization level used for mid-tier compilation, trading mid-tier compile cost against code quality.
0
Multi-Tiering remains disabled by default. Enable it with
-XX:+UseMultiTiering. See Using Multiple Compiler Tiers.
