Interesting project, Ali. Does the combination of agents work with other aspects, i.e. ones unrelated to the ASM-inserted method calls? I mean, does anything get woven at all? If so, my guess would be that the byte code ASM produces is not recognised as valid method calls by AspectJ. Otherwise there is another, more basic problem with mixing those agents. I never tried, actually.
