Just to add to Rick's comments. Where build time enhancement can really help you is if you run some acceptance or unit tests before deploying to Glassfish. It's always nice to test with the same bytecode that you deploy.
That said, it Glassfish should configure the automatic enhancement if you use a container managed EntityManagerFactory or EntityManager. It's not required to hook in a class transformer for enhancement if you use the javax.persistence.Persistence bootstrap class. So, like Rick said, taking the time to do build time enhancement can eliminate one more variant in your environment (and save some headaches).
