the Submit class takes a -p port argument.

However, there is no way to change the port of the server-side listener.

Add the ability to indicate a port other than the default port of 9091. From TransportListener.java:

...
public static int DEFAULT_PORT = 9091;
...
theServerSocket = new ServerSocket();
theServerSocket.bind(new InetSocketAddress("localhost", DEFAULT_PORT));
if (Transformer.isVerbose())

{ System.out.println("TransformListener() : accepting requests on port " + DEFAULT_PORT); }

A minimal solution would be to use a system property:

port = Integer.parseInt(System.getProperty("org.jboss.byteman.listener-port", "" + DEFAULT_PORT))
