So here's a question.  I see that OpenOffice and Firefox are both using
Java (ouch, this hurts).

I also see now that java_vm is not exiting even after the applet should
have finished running (this with the Blackboard applet that I have specifically
identified as problematic).

Can these ports use kaffe instead?  Or is there a way to force java_vm to
exit without my having to babysit it?  Killing java_vm takes down Firefox
as well.

And, is there a way to tell which other ports rely on java?

I see now that it is not.

I upgraded to RELENG_7 hoping to make a USB problem go away (symptoms
changed, but problems remain).  I did not experience the problem prior to
this upgrade.

I have now deinstalled diablo-jdk and:

earth# JAVAVM_DRYRUN="YES" java       

At the moment, I don't have a way to invoke the evil applet.  What I don't see
is where this configuration is; what you have above doesn't look at all like
the /usr/local/etc/javavm_opts.conf on my system.  Is this because you stripped
the comments?
