Crashes in Java

[sstirling at mediaone.net (Scott Stirling)]

I'm not too familiar with AWT and Swing, but here are some suggestions and
considerations:

1. Try running these apps with a newer JVM.  You're using an _old_ version
of 1.2 from Blackdown.  This means it likely has lots of bugs that have
since been worked out.  I'd highly recommend getting the 1.2.2 RC4 that came
out the other day.  That's your best bet for fixed Swing and other bugs.

2. Try running these programs without JIT enabled.  JIT can cause weird
problems, especially in an early beta like this JVM.  Running without JIT
will also show you line numbers in stack traces, but since these are Sun's
and someone else's apps segfaulting, there's nothing you could do to fix it.

3. Try running these apps with native threads instead of green.  Just
another blind attempt at reconfiguring the way the JVM's running, but it
could have a positive or detrimental effect.  Upgrading to an RC is better,
but it can't hurt to try running under native threads just to see what
happens.

4. Try an IBM JVM if you can run these with a 1.1 JVM.  Otherwise, forget
that one.
