Horrible as it sounds, my most effective debugging tool has been print statements
:-(. I tried jdb with the Sun SDK1.3 a few days ago, and had better success attaching
to a running process than I did launching the process from jdb. Overall, Java2
debugging on Linux is not in a happy state. (Neither is profiling, which works with
the "classic" JVM but not with HotSpot.)
