If you do not run persistence tests under entity-persistence-tests, please
ignore this message.
If you do, the fix for issue
https://glassfish.dev.java.net/issues/show_bug.cgi?id=1380
will require to remove the previously created tables before running the
changed tests.
This can be done either manually (long but safe), or via a new ant target
'ant clean-db' (quick but it'll drop all the tables, not only the ones created
by the tests, so be careful!).
