> The problem is that the test case for DERBY-5153 creates a table and doesn't
> drop it. testUpdateStatistics() checks the statistics for all tables in the
> database, and it will fail if the DERBY-5153 test case runs first (which it
> sometimes does on Java 7) because it finds statistics for tables it didn't
> expect to be there.
