Attached: it's a VM crash.  As soon as I can duplicate the test in a
debugger I'll be able to fix it.

I find it very difficult to run juinit tests because they don't really
expose what the VM is doing, and it's very hard to run them in a
single test in a debugger.  I'm sure they're not deliberately making
it hard, but it sometimes seems that way.

Thanks,

Andrew.
