Start by reproducing ErrorReportingSpec and inspect its actor-system teardown around CoordinatedShutdown. Trace the terminate-system failure and the InterruptedException shown in the stack trace. Done means ErrorReportingSpec completes without aborting and the actor system terminates without the warning.
