One problem with doing diagnostics for configuration failures and errors in the
underlying OS/JRE is that they are hard to reliably translate. If you look for
strings, your code breaks on every OS/JRE update. If you take a guess, you end
up with those windows programs that assume that all failures are due to being
out of memory, because that was a common fault. but if it isnt the fault, it is
even more misleading.

You bring up a great point, Steve. For this reason I'm convinced that perhaps
creating a better error message isn't the best solution.

What we can do is what you have done: place the stack trace on a bugrep where
it is searchable. The next time someone gets this error and searches for it.
they will find this page. So we should add the instructions on what to do to
make the error message go away.

In my case, I was working at a large corporation, and my IT department was
unable to resolve the problem. I had to drop the internal Ubuntu derivative,
along with LDAP, certain tools, etc, and switch to pure Ubuntu. My solution
was rather cumbersome, but I my efforts to Google for solutions to my problem
only led to dead ends and frustration. I even sent an email to the users list
with no luck.
