> Not re-injecting the interceptors for instrumented entities will cause NullPointerExceptions when entities get retrieved from a deserialized PersistenceContext. This manifests itself for example in the unit test EntityManagerSerializationTest in the entity manager module (when run instrumented of course).
> Currently the problem occurs in line 1406 of StatefulPersistenceContext: rtn.entitiesByKey.put( EntityKey.deserialize( ois, session ), ois.readObject() )
> I think FieldInterceptionHelper.injectFieldInterceptor should be called here. Something along these lines:
> Object key = EntityKey.deserialize( ois, session );
> Object value = ois.readObject();
> FieldInterceptionHelper.injectFieldInterceptor( value, value.getClass().getName(), null, session );
