Follow up: I have tested it with OpenJPA 2.3.0 and the error is still happening. :-( Meanwhile, I’ve put back the dependency to EclipseLink and the problem doesn’t happen in this case. That’s a pity because the environment I’m using (TomEE) has OpenJPA as the JPA implementation. It’s always good to optimise dependencies. The entity class is the following:
