The following test failed in my jdk-22+12 stress testing on linux-x64:

gtest/GTestWrapper.java

and it was the ThreadsListHandle.sanity_vm sub-test that failed.

Here's a snippet from the log file:

[ RUN ] AltHashingTest.halfsiphash_test_FromReference
[ OK ] AltHashingTest.halfsiphash_test_FromReference (0 ms)
[----------] 3 tests from AltHashingTest (0 ms total)

[----------] 1 test from ThreadsListHandle
[ RUN ] ThreadsListHandle.sanity_vm
open/test/hotspot/gtest/runtime/test_ThreadsListHandle.cpp:604: Failure
Expected equality of these values:
  tlh1.list()
    Which is: 0x5622071213c0
  tlh2b.list()
    Which is: 0x7f3e70024310
tlh1.list() must match tlh2b.list()

[ FAILED ] ThreadsListHandle.sanity_vm (1 ms)
[----------] 1 test from ThreadsListHandle (333 ms total)

[----------] 1 test from Align
[ RUN ] Align.alignments
[ OK ] Align.alignments (31 ms)
[----------] 1 test from Align (31 ms total)

This failure sighting happened in run#1 of 3 in the 'release' bits
config so this test passed 8 other times in this stress run.
