In working on the CTS, we've discovered some assumptions that cause
OpenJPA to fail. The CTS obtains records via calls to getReference(),
and then does some work with the objects.
The tests fail outright with default OpenJPA settings, as the
openjpa.DetachState property defaults to 'loaded'. Instances obtained
via getReference() have not yet been loaded, so there is no data
available when the instances are detached.
The tests can be made to pass by setting the openjpa.DetachState
property to 'fgs',
'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.
