   *
   * Actually, the collection is a wrapper of "org.hibernate.collection.PersistentCollection"
   * so it need not to implement that interface.
   *
   * But Hibernate.isInitialized(Object) and Hibernate.initialize(Object)
   * required that the collections are always implementations of

   *
   * If the class does not implement that interface, the

   * can cast the collection to "org.babyfish.model.LazinessManageable" and invoke its
   * isLoaded() and load().
   *
