Bryan Pendleton updated DERBY-1583:
-----------------------------------
Attachment: skipAddPriv_v3.diff
Mamta, thanks for the suggestion about DERBY-1724.
I think it is definitely another manifestation of the same bug.
Attached is skipAddPriv_v3.diff, which includes the DERBY-1724
test case as part of the grantRevokeDDL.sql tests.
I ran the DERBY-1724 test case interactively, and without the
patch I get the NPE, and with the patch I get reasonable results.
So I think that we can mark DERBY-1724 as a duplicate of this
bug, assuming that we decide to proceed with this patch.
Reviewers, please review skipAddPriv_v3.diff instead of the v2 patch.

> While working on SQL authorization work, I ran across a test case where Derby
> will throw a NPE when a trigger is defined with it's action as update a table
> from another schema. I don't have much details on why but following is the
> test case. Derby is trying to put privilege requirement for a column into
> privilege requirements list and it expects the column's tableUUID to be not
> null but in this particular case, it is null.
