Yes, all tests should pass without errors.

I think the TableFunctionTest is new, and there have been some issues logged
about getting it to run in various environments, so you may have found another
such problem.

I can see three possibilities:
  - there's something about your DERBY-3574 patch that is causing the problem, or
  - the patch is unrelated, and this problem simply shows up in your environment.
  - the test fails intermittently, and you are the first to notice it.

Can you:
  - back our your patch so you have a clean codeline (svn stat shows no changes)
  - re-run the tests

If the test fails again, it might be something about your environment which is
provoking this test to fail.

If the test passes on a clean codeline, but fails with your patch applied,
it might be something about your patch.

If the test passes sometimes and fails sometimes, and the pattern doesn't seem
to have to do with your patch, we'd have to do more work to try to figure out
what's causing the failure.
