Knut Anders Hatlen commented on DERBY-3764:
-------------------------------------------
Thanks Bryan, those are all good suggestions. I am planning both to investigate
why we don't see the execution problem with the original query, and to add more
tests. I'm not sure we can add the original query directly since the attached
repro wasn't licensed to the ASF, but once we find out what makes the
difference between the queries, it should be easy to add something equivalent
to it.
