I don't know what that is, but as far as I know dozer, it only does java object-to-object mapping. This has nothing to do with the actual JPQL/HQL query that gets executed in order to retrieve the entity classes. I need the actual HQL to be able to tell you what is happening.

By the way, if you are interested in doing the object mapping more efficiently give Blaze-Persistence Entity Views a try. I am the author of that library and have used it for doing efficient object mapping for quite a lot REST endpoints myself.
