I accidentally send this to Yonik directly -- forwarding to mail list.

An "around" advice and do that in a very flexible way and I have thought of that before. Personally I would prefer not to change the distributed jar file but rather plugging something in from the outside. This might be a personal thing but I can imagine that many users do not want to modify the binary distribution using a aspectJ or whatever implementation compiler to modify the bytecode.
