javax.persistence.PersistenceException: org.hibernate.type.SerializationException: could not deserialize

Question

When executing a Criteria Query in hibernate, I get the following exception:

javax.persistence.PersistenceException: javax.persistence.PersistenceException: org.         


        

Answer 1

The problem was that a referenced entity had another reference to an entity and the relationship was NOT annotated by any of the @OneToMany-like annotations.
