-----------------------------------------
Summary: Authorization decorators don't null out connections when
done
Key: DERBY-5705
URL: https://issues.apache.org/jira/browse/DERBY-5705
Project: Derby
Issue Type: Bug
Components: Test
Affects Versions: 10.9.0.0
Reporter: Knut Anders Hatlen
Assignee: Knut Anders Hatlen
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.
