• Any EclipseLink Bugs or Enhancements I am currently working on can be viewed on my LED display board on my cubicle wall - In case I forget over the weekend. The bug numbers are automatically downloaded from an eclipse web query every 15 min and downloaded both to the display controller (an 8 core parallel processor - 1 core/line and the 5th core for USB comms) and a server-side Derby database via an EclipseLink JPA based SE network application.

Concurrency Issues

UnOfficial

• Investigate EJB 3.x equivalent to cascade=CascadeType.SAVE_UPDATE? Is MERGE better than PERSIST? - see https://forum.hibernate.org/viewtopic.php?f=9&t=963665&start=0 and http://forum.springsource.org/showthread.php?t=85108
  • How can we use @PrivateOwned - discussed this with Guy - we need to managed the non-defaults for all CascadeType=, @OrphanRemoval=false and the opposite @PrivateOwned=false
  • Then respond to http://forums.oracle.com/forums/thread.jspa?threadID=2152045&tstart=0

Deferred but Very Important

• I would like to get some scheduled time to finally resolve the remaining workarounds for WebLogic 10.3.3.0 and JPA 2.0 for EclipseLink, Hibernate and Spring in http://wiki.eclipse.org/EclipseLink/Development/JPA_2.0/weblogic#TODO

Pending

• NetBeans and -javaagent

Raised

Bugs and Enhancements I am interested in

• The following have my interest, I may or may not be involved in the solution, or I may have the issue myself. Usually I add myself to the CC list on the Bug or ER.
• 336596: java.util.NoSuchElementException when using @ElementCollection for enum in Embeddable

Experimental

• Concurrency
• Thread safety
• Mixed JSF/Spring/AJAX/EJB framework artifacts

To Review

• Extensibility - Dynamic Data Model (required before implementing Multi-Tenancy
• Multi-Tenancy or SaaS Features and eventually PaaS aka EC2 a quick google search will come up with Analysis work done by Frederick Chong, Gianpaolo Carraro, Roger Wolter and Paul Henry at Microsoft in 2006
