applications/ml/MLSamples.java timed out with core file

The following test timed out in the JDK19 CI:

applications/ml/MLSamples.java

Here's a snippet from the log file:

[stress.process.err] INFO: At iteration 33000, average loss = -0.005821266962157271

[CrashDetector] Found .core: ./core.8284
[CrashDetector] WARNING: STRESS PROCESS CRASH DETECTED!
----------rerun:(36/7931)*----------

So the CrashDetector found a core file, but there is no hs_err_pid
file for this sighting.

I'm starting this bug off in hotspot/test for initial triage. I'm not
familiar with this test and I don't know what's happening here.
