  • Hibernate4.3.1 with Spring3.1.1/JPA2.1-Found shared references to a collection error

    I am working on Hibernate upgrade in my project. We were on hibernate 3.3.1, spring version 3.1.1 and working with JPA 2.0 as persistence layer. Now I am trying to upgrade Hibernate 4.3.1. I have done all necessary dependencies for this upgrade.

    I am able build my project fine but when I run our JUnit tests, am getting Found shared references to a collection error (I have upgraded to Hibernate 4.3.1 with JPA 2.1 and Spring 3.1.1 in our project now). Can you please help me to solve this error .

    Caused by: org.hibernate.HibernateException: Found shared references to a collection: com.carlson.cwt.portrait.domain.traveler.BusinessT raveler.addresses

    My mappings are as below between BusinessTraveler and TravelerAddress:

    in BusinessTraveler class:
    @OneToMany (cascade = CascadeType.ALL, orphanRemoval = true, mappedBy = "businessTraveler")
    private Set<TravelerAddress> addresses = new HashSet<TravelerAddress>();

    in TravelerAddress class:
    @ManyToOne
    @JoinColumns ({
    @JoinColumn (name = "BUSINESS_TRAVELER_ID", nullable = false, insertable = false, updatable = false),
    @JoinColumn (name = "BUSINESS_TRAVELER_ORIG_ID", nullable = false, insertable = false, updatable = false) })
    private BusinessTraveler businessTraveler;

    Is this Found shared references to a collection occurs due to mappings? or because of some else in project??
