Adding the comp:jit label since no failures were observed in the 100x grinder run with -Xint: https://hyc-runtimes-jenkins.swg-devops.com/job/Grinder/51368.

The test failure does not appear to be related to JDK 24 virtual threads (JEP 491). Moving this issue to the 0.53 release.

fyi @hzongaro

[hzongaro]

@luke-li-2003, may I ask you to look at this? It looks like this failure first occurred after #21097 was merged, and the array access that is throwing the ArrayIndexOutOfBoundsException is using the result of a call to ArraysSupport.vectorizedMismtach.

[pshipton]

This seems like a regression from jdk23, which should be in the jdk24 milestone plan. Is https://github.com/eclipse-openj9/openj9/pull/22209 related?

[luke-li-2003]

That is possible, I have not been able to reproduce it yet.

[pshipton]

Try 50x (10x x 5) on alinux,zlinux,xmac on the last nightly build, which doesn't contain https://github.com/eclipse-openj9/openj9/pull/22209 yet. I set exit on failure. https://hyc-runtimes-jenkins.swg-devops.com/view/Test_grinder/job/Grinder/53542/

[pshipton]

The grinder passed so this seems to already be resolved.
