Thanks, Manish. I can add the new canon myself. I just want to make sure that you've seen and understood this diff and don't regard it as a regression.

Re: [jira] Commented: (DERBY-578) Grouped select from temporary table raises null pointer exception in byte code generator
Since only predicatePushdown failed, I generated a context diff for this one file. I already have a bunch of other uncommitted changes in my view, so I'm not sure how I can generate one patch file without pulling in a lot of other stuff. The following sequence of steps should work. 1. Apply the complete patch (578.patch.txt). 2. revert predicatePushdown 3. patch predicatePushdown.

It looks like it might just be the changes to predicatePushdown.out. Could you give me a single patch file which contains everything I need to apply this patch and which I can apply with a single patch command?
