When I add the following Java options to enable debugging:
JAVA_OPTS=\"$JAVA_OPTS -noverify -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_soc
The problem is your tomcat is still running on the debug port(5005) or some other service running on the same port(5005).
If tomcat still running, you can kill it
Now you should be able to start the server in debug mood without any prob.
This can happen on debugging unit test through the tool(eclipse) which has been executed through the maven. To sole this you can flow the same process.
First close the Eclipse and kill the java process as well and start it again.
