> Project: Derby

> Components: Test
> Affects Versions: 10.9.0.0

>
> Some decorators used to test authorization don't close and null out
> references to Connection objects when they have completed. Since these tests
> often create/boot single-use databases, and the Connection objects have
> references to the database instance and, directly or indirectly, many of its
> modules, this prevents much garbage from being removed from the heap after
> the tests have completed and shut down their single-use databases. We should
> close the default connection and clear the reference to it when tearing down
> these decorators, so the space is released for subsequent tests to use.
> This problem affects decorators returned by the following methods:
> DatabasePropertyTestSetup.builtinAuthenticationNoTeardown()
> TestConfiguration.sqlAuthorizationDecorator()
> TestConfiguration.sqlAuthorizationDecoratorSingleUse()
> These methods return modified versions of DatabasePropertyTestSetup where the
> tearDown() method is a no-op.
