Possible upstream problem with virtual threads.

Possible upstream problem with virtual threads.

I have seen this as well, and I agree with your diagnosis. The Loom merge caught me by surprise. Between that and the Panama one, there are suddenly a large number of failing tests that need to be added to a ProblemList.txt, and fixed.

I will open a PR shortly.

This is solved on my machines by openjdk/jdk#8939. The ~3 core files I see appear unrelated to vthreads.

[aixtools]

recommend closing this as jdk19 is AIX 7.2 only moving forward.

@sxa - considering @backwaterred comment: can this be closed?

[sxa]

Seems fair.
