I have such kind of @OneToOne Hibernate relationShip
public class Address implements Serializable { private String id; private String city; priv
The easiest solution: Don't serialize entities, use Value Objects.
If that is not an option for you, make sure that the entity Object is detached.
With JPA (2), you would use EntityManager.detach(entity), with plain Hibernate the equivalent is Session.evict(entity).
