    StackOverflowError : Can't save object with Envers

    Sylvain Blanchon Newbie

      Hi,

      I have a problem with Envers and auditing entities. I have an existing application which, unfortunately, isn't really well built, and I'd like to apply envers on it.
      Hibernate was already working properly.

       

      Envers is configured correctly (or at least I believe so) with these properties in the hibernate.cfg.xml :

       

      <property name="org.hibernate.envers.audit_strategy">org.hibernate.envers.strategy.ValidityAuditStrategy</property>

       

      <listener class="org.hibernate.envers.event.AuditEventListener"type="post-insert" />
      <listener class="org.hibernate.envers.event.AuditEventListener"type="post-update" />
      <listener class="org.hibernate.envers.event.AuditEventListener"type="post-delete" />
      <listener class="org.hibernate.envers.event.AuditEventListener"type="pre-collection-update" />
      <listener class="org.hibernate.envers.event.AuditEventListener"type="pre-collection-remove" />
      <listener class="org.hibernate.envers.event.AuditEventListener"type="post-collection-recreate" />

       

      The auditing tables are created and populated with a copy of the tables, and a foreign key to an existing revision.

       

      None of the audit works, and here is an example :

      I want to create an object "FAQ". It has two String field, and a many-to-one relation with the object "User"."User" has 12 one-to-many relationships, 1 many-to-one and 3 many-to-many.

      In order to save the "FAQ" object, I have to set its "USER" field, with the one retrieve from the database :
      faq.setUser(userDao.getUser(id));

      I think the following error comes from the relation between the object, but I can't really figure out why.

       

       

      The error occur when I try to save the faq object :

           at java.util.MapEntry.hashCode(MapEntry.java:75)

           at ....

       

      And so on. The only interesting information I've been able to extract is this part :

      I can't figure out why there's a stackOverflowError when I add Envers and auditing to this simple object. This error occurs for every entity I try to save.

      Thank's in advance, if you need more details, I'll answer as quick as I can.
