      This ClassCastException occurred in the following test scenario:

      (1)
      @Entity
      public class EntityA implements Serializable {
      @Id
      Integer id;

      @Embedded
      EmbedA embedA;

      ...
      }

      (2)
      @Embeddable
      public class EmbedA {

      @OneToOne(mappedBy="a", fetch = FetchType.EAGER, cascade = CascadeType.ALL)
      EntityB entityB;

      ...
      }

      (3)
      @Entity
      public class EntityB {

      @Id
      protected int id;

      @OneToOne
      private EntityA a;
      ...
      }

      (4) test case:
      EntityManager em = emf.createEntityManager();
      EntityA a = em.find(EntityA.class, 1);
