The behavior since JDK 9 is to delete the temporary file when there is 
an error. This looks to be the correct behavior. If it were changed back 
then people would complain that jar is leaving files behind when it fails.

I'm curious how you run into this. Is this a script that runs with +e or 
doesn't check the exit status?
