Attached is thread from nbj2ee discussing this bug. I haven't narrowed down
exact steps to reproduce, but I do know the code path that is being taken that
causes this (and thus I can fix it, just not sure exactly how I'm going to do
that yet.)

-------------------------------------

Thanks, these are roughly the scenarios where it seemed this might happen.  I
have not been able to reproduce it through my own tests, but I can see the code
path that allows it so I will come up with a way to fix it.
