Actually, what I said is that you should launch from the java debugger and
later go on and from your code call pydevd.settrace() to attach to the
remote debugger.

I think that doing it the other way around and passing additional arguments
to the java and attaching the java debugger as a remote debugger should work
too... But one of those should be the remote debugger...
