The following test fails intermittently in my stress runs:

runtime/Safepoint/TestAbortOnVMOperationTimeout.java

Here's a snippet from the log file:

JavaTest Message: Test threw exception: java.lang.RuntimeException
JavaTest Message: shutting down test

result: Failed. Execution failed: `main' threw exception: java.lang.RuntimeException: Expected to get exit value of [0]

Please note that this part:

# Internal Error (/System/Volumes/Data/work/shared/bug_hunt/thread_SMR_stress/jdk19_exp.git/open/src/hotspot/share/runtime/vmThread.cpp:91), pid=93202, tid=12803
# fatal error: GenCollectFull VM operation took too long: completed in 64196 ms (timeout: 63423 ms)

is NOT the error. The test is trying to prove that "Internal Error"
occurs and the actual test failure is the:

exitValue = 1

Please note that I have not seen this failure outside of the
stress testing runs in my lab.
