Knut Anders Hatlen updated DERBY-2149:
--------------------------------------

    Derby Info:   (was: [Patch Available])

I reran the JUnit tests and got two failures in the nist suite. They seem related to the patch,
so I'm removing the patch available flag for now. Will investigate the failures later.
