I have used aspectj in somewhat unhealthy dose in my project. Mostly for reasons not even intended as an use to aspect. We have to work on giant configs reified as giant java objects. And I have was able to collect enough metadata about the code using aspects and keep them tied to the live objects in such a way that I was able to simulate creation, transformation and move of method calls. yes, a byte code parser and reflection might have achieved the same, but the library made it breezy. Maybe, java is not a hacker's language but ecosystem comes with hackers toolbox.
