Please review the change that fixes intermittent failure of
java/lang/management/ThreadMXBean/MaxDepthForThreadInfoTest.java
As David noticed (thank you, David, for this analysis) there is no guarantee
that all threads found by getAllThreadIds() are still alive by the time we call
getThreadInfo() so we have to allow for null array entries.
Testing: Mach5 tests with Graal on passed 300 times.
Fix looks good - thanks.
I think it would be informative to actually determine which thread(s) is
disappearing (not as part of the test just as some diagnostic info to
add to the JBS issue). Can you reproduce the failure easily?
Thanks,
David
