I was aiming for an event from the first thread starting the shutdown sequence, as I think that’s probably the one you are looking for if you are diagnosing an unexpected shutdown. Any event generated after that point may not make it into the recording as the tracing framework shuts down from a shutdown hook.

If finalizers on exit go away, is it still possible that the thread starting the shutdown sequence isn’t the one eventually calling JVM_Halt (in the absence of calls to Runtime.halt)?

Best regards,
Robin
