Anurag Shekhar updated DERBY-3330:
----------------------------------
Attachment: derby-3330v13.diff
changes in derby-3330v13.diff
1. replaced uniqueWhenNotNull by uniqueWithDuplicateNulls.
2. added description about relation ship between unique and
uniqueWithDuplicateNulls.
3. Added entry for NullableUniqueConstraintTest in lang._Suite (this was lost
due to one of the conflicts)
Upgrade test (from 10.3.1.4) runs without failure.
lang._Suite fails with 6 failures in LangScripts. I am getting these failures
in fresh work space. (few hours back there was no failures in lang._Suite)
> provide support for unique constraint over nullable columns
