Does this mean that the upgrade test is going to fail until 10.1.3 is
released and the jars checked into the repository? If that's the case,
I think we should update the upgrade test canon temporarily now and
revert it once 10.1.3 is out. Ole's tinderbox test has failed since
the check-in of this patch.

> I have a database with a large number of tables.  I get duplicate rows when I call DatabaseMetaData.getImportedKeys
for a particular table. However, if I create the same table with same number of foreign keys
in another database (which has fewer number of tables), then getImportedKeys returns me the
correct number of rows. This error seems to happen only when the database has a large number
of tables. I will attach a repro for this shortly.
