AspectJ also does a pretty good job. But all in all, it depends what you want to extract from the execution. Which kind of metric or data are you interested in ?
We are currently writing an agent for the JVM to extract low level data.

Hi,
I am interested in the exact traces including distinguishing between different clients and different threads.

AspectJ sounds like what you need, but I am not familiar in that area.

In reply to this post by Tudor Girba-2
As Alex mentioned, one option would be to roll your own using AspectJ. If you just need a log to a file with all called methods, recieviers, arguments and the executing thread, this should be quite trivial. I guesstimate that 50 LOC should be an upper bound.
