No it is a normal java application (The GWT debugger).

The GWT debugger is completely agnostic with regards to what serves the host 
page. The GWT debugger is connected to the browser, not the server. The host 
page can be served from a local JBOSS, a remote Apache, a file, whatever. The 
GWT debugger doesn't care as it is talking to the browser.

IMO the only thing we could do to improve this is update the make file to 
provide a target to start the debugger, which basically just calls maven with 
the appropriate parameters.
