'loaded' is the proper default.  If the CTS is relying on any state  
being loaded after a call to getReference(), then those CTS tests are  
wrong and should be reported as such.  The description of  
EntityManager.getReference explicitly states that state might be  
lazily fetched and that you can't rely on the state being available  
on detach unless you've accessed it.
