    Yes, it is for POJO support (not only JPA). I.e. at compile time your
    classes may not implement Persistent. I already ran into problem with
    POJO integration tests with "newObject" returning Persistent that is
    being assigned to a concrete type that is not Persistent at compile
    time.
