11:30 - 12:00API Design and Forwards-CompatibilityOpenJPA has a number of APIs that we expect to be visible to developers. These should be stable over time, and should be well-designed to meet the needs of our developers. This is currently not always the case (OpenJPAEntityManagerFactory extends a billion interfaces, for example, our event frameworks sometimes require code changes for people who implement the event interfaces, and we use a combination of enums and symbolic constants even in our org.apache.openjpa.persistence interfaces). I'd like to discuss this to raise awareness about the issue, and also discuss how to improve things in the short term. I'd also like to bring up the idea of an API jar that should contain enough for the average development team to link against.Patrick LinskeyPatrick LinskeyAPIDiscussionFollowUp

The sponsor is the person proposing the agenda item, and is responsible for making sure that a given agenda item actually happens. The sponsor is not necessarily the person actually presenting / leading the discussion for a given item.


BEA headquarters in San Jose (near SJC) 2315 North First Street San Jose, CA

There is plenty of parking. The meeting room is in Building 1, which is the further-south building, abutting both First Street and Charcot Avenue. If you drive up First Street from the south, your best bet is to turn left on Charcot and then right into the parking lot. The receptionist in Building 1 will point you in the direction of the conference room.

We have wireless internet available, so it should be easy to stay in touch in the break periods. Hopefully, all the sessions will be sufficiently riveting that nobody will be playing around on the internets during the sessions.
