The no-arg constructor can be private.

fine - is this an OpenJPA specific feature or part of the JPA spec? You have to know: in our current EJB2.1 CMP EB implementation,
we - unconsciously - used a lot of not-spec-compliant stuff which inhibits deployment of our .ear project to another J2EE1.4 container
- that's one of the reasons we're migrating to JPA.... but in this case, I'd like to stay spec conformant if possible.

anyway - thanks for the tip!
