Since upgrade to Java 17, VARS experiences random, intermittent crashes #131

This has been reported by both MBARI and DARC. It looks like this is due to a bug in the JVM, see https://bugs.openjdk.java.net/browse/JDK-8283386

All,

Thank you very much for all the comments/suggestions. I have been learning a lot about JVM C2 compilation the last couple of days.

BTW, in the meanwhile a similar bug has been reported with Debian Linux and has been added to https://bugs.openjdk.java.net/browse/JDK-828338 https://bugs.openjdk.java.net/browse/JDK-8283386.

I would like to briefly summarize what my solution is for the time being. Since in my case stability is much more important than speed I used a rather radical approach to prohibit C2 to do any aggressive optimization.

-XX:+TieredCompilation (enable C1)
-XX:TieredStopAtLevel=1 (disable C2)

It seems somewhat similar to the out-dated "-client" option. The application didn't really feel any slower. However, that certainly depends heavily on the use case.

Note: I very much look forward to the day the GraalVM compiler gets the default.

Hope this might be useful for others.

Thanks,

@SarahRDBIngo Try out release 1.1.14 and see if it addresses the random crashes you were running into.

The video lab at MBARI has reported that there are no longer any crashes with 1.1.14. Looks like disabling the C2 JIT compiler addressed the issue.
