 Description  « Hide
JDO (in DataNucleus) has always defaulted to pessimistic transactions (though by default NOT locking objects). This originated in not supporting optimistic transactions back in the early JPOX days. JPA defaults to optimistic, and makes sense to to do the same for JDO.

Still got various tests that show side issues with moving to optimistic as default, so postponing
