fails with an exception because the classloader code is

Thanks for reporting it, but it's an old bug see here:

http://sourceforge.net/support/tracker.php?aid=1448738

I've filed a bug report against JDK 6.0 for this issue
(For more details, see the link above)

OK, so I just went back and read the evaluation given for the
bug report I filed with Sun and it appears there is a fix
which is permanent, that I have tested and will become
available in the next snapshot. See the original SQuirreL
bug (1448738) where I'll detail the fix that was implemented.
