Mike Matrigali updated DERBY-3330:
----------------------------------
I am running a set of tests on the v9 patch and will post results when they are
done. I am reviewing the v9 patch currently, but will likely concentrate on
the store level changes. If there is anyone with time to review the language
level code that would be good. Especially would like help verifying that the
language catalog upgrade code looks right - I have not done that before.
> provide support for unique constraint over nullable columns
