The following test failed in the JDK17 CI:

applications/kitchensink/Kitchensink.java

Here's a snippet from the log file:

The tail of stress stdout is:
For random generator using seed: -2864060814175125206
To re-run test with same seed value please add "-Djdk.test.lib.random.seed=-2864060814175125206" to command line.
Stress process main method is started.

This bit from the hs_err_pid file:

RIP=0x00000193663a0f87 is at code_begin+4359 in an Interpreter codelet

indicates that we crashed in the interpreter so I'm starting
this bug in hotspot/runtime for initial triage.
