Eclipse/maven-jetty plugin: Couldn’t restart my listener

related to my blog: Eclipse: running your project via mvn jetty:run and debugging it

So there i was using my eclipse, running the external tool for debugging.
I recompiled my source code and needed to re-run the debugger.
But when I restarted the listener(part of external tool) it wouldn’t start.
My guess was on the port. So I asked nap…

checked it with lsof -i :4000

it returned the process running using it.
i guess eclipse was unable to kill that process, when i restarted my listener.
after knowing the PID i then killed it and started my external tool.

thanks nap.
