Description James Sutherland CLA 2011-03-28 15:36:32 EDT 
We should provide an option to deploy/connect session when EntityManagerFactory created, not EntityManager.

Currently we deploy when the em is first accessed, this makes the server start quicker, but means the first request could take a very long time, and possibly timeout.

It also causes an issue that each connection pool is validated on connect, binding each to the current JTA transaction.  This will break if a LLR optimization is being used.

Code review: Andrei, pending
Changes:
- Added "eclipselink.deploy-on-startup" option to deploy and connect persistence unit when factory is created, instead of when first entity manager to avoid JTA issues with multiple connections.
- Fixed bug in batch fetching using IN when multiple pages are required.
- Fixed bug in partitioning to use default connection instead of all write connections.
- Added test for field access to interface impl.
- Added batch fetch tests.
- Fixed annotation processing to use correct weaving flags.
