In a code review of an application using OpenJPA 2.1.1 with persistence mapping by annotations, I've just come across an entity class with a non-primitive field which is not annotated:
private MyInterface myInterface; I would have put a @Transient annotation on that field (or better still, removed it from the model), but what surprises me is that OpenJPA silently treats this field as transient and does not complain about a missing @Transient annotation. We use build time enhancement, and I can see no warnings from OpenJPA either at build time or at run-time. According to the JPA 2.0 spec, section 2.3.1, "all non-transient instance variables that are not annotated with the Transient annotation are persistent.", so I'd really expect OpenJPA to complain that MyInterface is not mapped. What do you think? Best regards, Harald
