Save can fail when there is a transient entity reachable by multiple paths and at least one path does not cascade on save
-------------------------------------------------------------------------------------------------------------------------

                 Key: HHH-5784
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5784
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
            Reporter: Strong Liu


This issue is the same as JBPAPP-915, but is for the save event. It may also affect persist and save-update events. 

The fix should be very similar to what was done for JBPAPP-915 and one fix may work for all of these types of events. 

This issue needs to be fixed to support JDK 1.6. Because the iteration order for HashSets and HashMaps is different for JDK 1.6, cascading operations to entities in a set may be saved in a different order, causing a cascade that worked in a previous version to fail with a TransientObjectException. 

See HHH-3229 for details. 

In addition, a note should go into the release notes that the change in order of cascades is a known issue.
