Hi, Try the weaver referenced in this thread: http://dev.eclipse.org/mhonarc/lists/aspectj-users/msg13370.html
Let me know if that works for you. The changes did not make it into 1.7.2, they were kind of 'misplaced' in the move from cvs to git, but I just found them again on my hard drive so if it works for you, I'll try and roll it into the next version.
