Right... It would be great to have the tests done and be part of
derbyAll.  But not sure if adding of new tests should stop development
that passes current Derby checkin criteria of clean derbyAll.

This is a good suggestion... It should be good to ask for this test to
be run as part of metadata changes?

What was the code change that caused this problem in 5.1? You have
provided symptoms of the problem. It would be good to understand the
code change that cause this symptom.

Again, I am not sure if DERBY-1107 should stop metadata developments.
Wasn't this "issue" present from the beginning?
