> BaseJDBCTestCase.getDatabaseProperty() creates a PreparedStatement and a ResultSet that
are not closed before the method returns. If a test case calls getDatabaseProperty() many
times, the open statements may have a big memory footprint.
> This can be seen for example by running jdbcapi.AuthenticationTest with -Xmx64. It will
fail with an OutOfMemoryError when testNoCollisionsWithConfigurableHash() runs in client/server
mode.
