Re: [aspectj-users] Weaving classes in rt.jar
|
You can try weaving the calls to HashSet.add, rather than the executions
something like:
call(HashSet+.add(..))
Of course this would not advise calls to add() inside of rt.jar (are
there any?) or calls in third party libraries that aren't woven by
you.
