Hibernate: org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session


I strange why this exception occurs although it is assured by Hibernate get/query methods to recover objects that are already available inside the Hibernate session in case those objects are needed repeatedly:
org.hibernate.NonUniqueObjectException: a various object with the similar identifier value was already associated with the session: x.y.z.MyObject#130062
