A B resolved DERBY-3279.
------------------------
Resolution: Fixed
Fix Version/s: 10.3.2.2
Thanks for the feedback, Ajay. I committed the changes to 10.3 with svn #
619568:
URL: http://svn.apache.org/viewvc?rev=619568&view=rev
> I would say that we can put this bug to bed.
Since it's in 10.3 now, I'm marking the issue as resolved. If all is okay, can
you go ahead and close it when you have the chance? Thanks again for your
patience on this one...
