I haven't built the tests to reproduce locally, but a possible cause is #20695.

Attn @mpirvu.

[github-actions]

Issue Number: 20798
Status: Open
Recommended Components: comp:jitserver, comp:jit, comp:vm

[mpirvu]

@luke-li-2003 Could you please look into this crash? I don't have reasons to believe that #20767 is going to fix it. Thanks

[luke-li-2003]

This is odd. This looks like the error I fixed with #20698, which got reverted by #20685.

[mpirvu]

@luke-li-2003 If your fix got reverted, please talk the the author to make sure it was a mistake and not something intentional.

[mpirvu]

That's a big commit. Let's make sure that some of your other changes were not removed my mistake

[mpirvu]

This method:

TR_OpaqueClassBlock *
TR_VectorAPIExpansion::getArrayClassFromDataType(TR::Compilation *comp, TR::DataType type, bool booleanClass)

will not work with JITServer.

[mpirvu]

Also a new
TR::VMAccessCriticalSection getClassFromSignature(fej9);
in
TR_VectorAPIExpansion::boxChild(TR::TreeTop *treeTop, TR::Node *node, uint32_t i, bool checkBoxing)

[knn-k]

@gita-omr FYI.
