Minor Description
The tests memory.BlobMemTest and memory.ClobMemTest have a tearDown() method that looks like this:
public void tearDown() throws SQLException
{ rollback(); }They should also call super.tearDown() in order to perform some additional clean-up (like closing of connection and statements). Since the tearDown() method in BaseJDBCTestCase will also take care of calling rollback() on the connection, there's not actually any need for a specialized tearDown() method in these tests, so I suggest we just remove the methods and let the classes inherit the method from BaseJDBCTestCase.
