@dholmes-ora - Sorry I missed this comment:

This test stresses getThreadInfo() and ThreadInfo.getLockOwnerName() as a
JavaThread is exiting. Similar to other stress tests that I wrote for M&M in the
Thread-SMR project, but this one is targeting getting the lock owner name as
the lock owner thread is exiting.
