[hibernate-issues] [Hibernate-JIRA] Created: (HHH-4737) Cache the EntityKey in EntityEntry when id is non-null

[Gail Badner (JIRA)]

Cache the EntityKey in EntityEntry when id is non-null
------------------------------------------------------

                 Key: HHH-4737
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4737
             Project: Hibernate Core
          Issue Type: Improvement
            Reporter: Gail Badner
            Assignee: Gail Badner


The EntityKey can be cached in the EntityEntry when the ID is non-null. This would help when a method already has an EntityEntry but needs an EntityKey (e.g., to look up a proxy in the persistence context.

I'm not sure if this is really worthwhile, but I'll attach a patch that shows how it can be implemented and where it can be used. It can also be used in some code I'm working on for read-only proxies.
