Looks like port 6606 is used for both JDPA (remote debugging) and the gRPC server. If that's true you want to use a different port for remote debugging. See https://docs.oracle.com/javase/7/docs/technotes/guides/jpda/conninv.html . Your remote debugger should then also connect to that different port.
