I'm pretty sure that the debug port is not enabled by default. You have to enable it via the -Xdebug parameter. Here is an example how to start java with enabled debugging and port 8000 as debug port:

As per Stefan Endrullis suggestion, This was my solution:

-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=8000
