JPA tests pass

[Andrus Adamchik]

It took me a while to bring our JPA code in sync with the final  
release of the spec. Now all the unit tests pass again. This is not  
to say that the provider is done :-)

Also there was some parallel effort going on to get access to the Sun  
J2EE TCK. Unfortunately (and quite surprisingly to me) there was  
deafening silence from the ASF individuals who are dealing with TCK  
issues. Wonder why?
