Current behaviour will recognise missing file as an error but continue processing and not produce the archive. Updated ClassPath test to verify jar is not created.

This one probably needs discussion to decide if the JDK 8 or current behavior is the right behavior. Once agreed then we will need to add tests to ensure that the behavior doesn't change, and maybe an update to docs too. Have you dug into the history to see if this behavior change was deliberate or just not noticed before now?
