Hi,

removing IProject isn't really an option as it is the only entity class so far. The other yet to come entity classes will be designed with the same pattern (see previous post).
However, after doing so it works.

Yes, all three points are true for my environment.

Cheers,
Rüdiger

Hi,
  To narrow the problem, I will suggest to suppress/remove IProject to see
if that changes anything.

Are the following statements true for your environment?
1. the persistent classes are not specified at <class> tag of
persistence.xml but specified as Map before construction of EMF.
2. The persistent classes are not enhanced at bulid-time. -javaagent is also
not activated. OpenJPA should subclass these persistent classes to manage
them.
3. the persistent classes may be loaded by different classloaders

  If they are, you have an interesting requirement -- your experience will
be useful to others.
