I have a basic maven job that builds my code.
Occasionally I was having an out of memory exception which fails my build.
The issue however is that while the build fails, the jvm would still be running after the build fails, and any ports that were bound will stay bound in CLOSED_WAIT state. This would cause all subsequent builds to fail as the port is already bound.

From my point of view it seems that jenkins is not properly cleaning up in this case.
