Hmm, you can step into rt.jar with a debugger, and if you have the 
source loaded it will at least show you what lines are executed branches 
are taken (although local variables have been optimized away).

I've also accidentally enabled "FINEST" level of debuging for java.* 
files and gotten quite a lot of spew.  That won't work if the classes 
you are interested in don't log, but it might be worth a shot.

I don't know of anything that specifically does what you want, although 
if you look into aspect oriented programming I think they might have 
something there that can auto-magically instrument a .jar file with 
logging.  This would be a lot easier than trying to do the byte code 
re-writting yourself.

Can you tell us specifically why you need this?  What's the use case, 
model, or failure mode here?  You question is kind of general.
