Reworked integration test to make it work on EclipseLink, too. Simply checking for new no joins doesn't work here as it even adds joins for plain attribute traversals using root.get(…). We're now using Mockito to verify the expected behavior on the interaction level instead of the Root's state. Removed superfluous finals. Added some Javadoc where necessary.
