> Hello Roger, do you think including the exit code in this System.err.println message would be useful too? That would then mean that if the Logger failed for whatever reason, this fallback message would at least include the exit code to provide some hints on what might have triggered the exit.

Including the status is simple enough, but has little/nothing to do with why the logging call failed.
