AdviceAdapter's exit advice may trigger multiple times

I recently tried to use AdviceAdapter from ASM Commons to insert a bit of code that would run before a method exited. It was important that the new code run exactly once no matter what happened inside the original function. Unfortunately the adapter seems to call onMethodExit right before every return or throw instruction. Advising on returns is fine, not so much on throws because the exception could be caught inside the method. Checking for containment in a try block would not help without some serious rewriting because a called function could be capable of throwing multiple types of exceptions, only one of which might be caught by the function being instrumented. So in AdviceAdapter's defense, its job is essentially impossible. I ended up renaming the original method and generating a "bridge" method with a simple try-finally around the call to the original.
