FWIW, I ran a Java app under the Linux JDK 1.3.0 earlier and it didn't crash, but it generated a console error message about a "troublesome thread" and about brought the machine to its knees. I tried killing processes, but system response was awful, and told it to shutdown. Shutdown took over 5 minutes on an 850 MHz Athlon.
