      The failure is caused by this assert:

      assertTrue(s.created.before(now));

      It might be a coincidence, but it happened the same night as Europe was switching from DST.

      It may also be related to DERBY-5046, where a similar assert failed because poor clock resolution made the two timestamps equal.
