8327990: [macosx-aarch64] Various tests fail with -XX:+AssertWXAtThreadSync

[reinrich]

I would like to backport openjdk/jdk22u@0c57256 to jdk 21 to get clean testing with -XX:+AssertWXAtThreadSync and avoid crashes because the VM is entered with the wrong WXState. The latter is very unlikely nevertheless aiming for clean tests with -XX:+AssertWXAtThreadSync will help to reduce the probability that users are affected by regressions in this area.

Testing:

I've verified every added WXState change if it is actually required.

The fix passed our CI testing with AssertWXAtThreadSync enabled: JTReg tests: tier1-4 of hotspot and jdk. All of Langtools and jaxp. JCK, SPECjvm2008, SPECjbb2015, Renaissance Suite, and SAP specific tests.

I don't understand this comment. Why does issuing a notify need WXWrite?

[reinrich]

The comment is preexisting. Issuing notify doesn't need WXWrite. It needs a thread state transition ThreadInVMfromNative and that transition requires WXWrite.

[theRealAph]

OK. I hate the way this code works, but we need it now.
