OK, it failed just now even with the “isJVMStarted()” in place on my Ubuntu setup:

Fatal Python error: Segmentation fault

Thread 0x00007fbca3605740 (most recent call first):
  File "/usr/local/lib/python3.8/dist-packages/jpype/_core.py", line 322 in _JTerminate  <<< line number changed because of inserted isJVMStarted().

Again, it must have run without issue several hundred times before this point.

Interestingly, my MacOS-based colleage is regularly seeing what we think is the same issue, and he was able to extract a crash log: hs_err_pid53983.log. This repro is from the cycling of Celery workers, with the SIGSEGV at process exit (or at least we assume so, since it has no discernible effect on the operation of the system). Note: he does not have the inserted isJVMStarted().
