Hi Bernhard, You could refer to my article here for all the debug options around ltw:
http://andrewclement.blogspot.com/2009/02/load-time-weaving-basics.html Beyond -verbose it talks about -debug - this option will actually tell you what classes are being passed to the weaver for weaving. I'm sorry I can't answer specific info about JBoss though, there may be something extra that needs configuring if it is using some kind of unusual classloader hierarchies.
