A-ha! When I faced those issues, I googled and I found a lot of people facing issues with weaving into the JDK so I thought it was an actual limitation of AspectJ. But from what you say, it seems like the only problem has to do with loadtime weaving but instrumenting a JAR should be fine.
Well, that's certainly good news and tomorrow I'll give it another try. Maybe this exception I'm facing has to do with something else... Anyway, thanks a lot!
