EclipseLink 2.1: Advanced JPA

This page captures the work planned for EclipseLink 2.1 under the them of advanced JPA. The goal is to increase the number of advanced ORM features that can be accessed through JPA leveraging standard extension points, custom annotations, and custom XML.


  • Historical EntityManager
  • EMF Broker


  • Additional Join (filter) on entity types and relationship mappings
  • Instantiation Policy
  • Historical Mapping
  • Unary Table Sequencing


  • Define additional FetchGroups using annotations or XML
  • Additional operators
  • user defined operators

Eclipselink ORM

The following bugs are the current prioritized list of features that are to be worked on for the 2.1 release. NOTE: The complete list will not be completed. The list is worked on sequentially and potentially re-prioritized after a release. Bugs are ranked with a 1 through 5 priority which breaks down as follows:

Priority Description
1 Must have for next release
2 Important for next release
3 Nice to have for next release
4 Unlikely for next release
5 Future

Individual bugs will contain more information on the design and implementation. Queued bugs may not have any extra information at this time and are populated once those bugs become actively worked on.
