[hibernate-dev] JPA callback listeners and CDI

[Steve Ebersole]

Recently I just finished up adding JPA 2.1 support for CDI injection of 
callback listeners.  Couple of things about this:

1) Took this opportunity to refactor and clean up a lot of this code. 
On benefit of this was I added a feature now where after transaction 
hooks are not added as part of ActionQueue processing unless registered 
listeners say it is needed for that particular entity type!  This is 
something users have been asking for for quite some time.  So thats a 
good win.  This is both for Envers and HEM.

2) The way this is currently implemented, using JPA now has a dependency 
on the CDI API being available on the classpath.  We need to decide if 
that is unreasonable.  The other option is to handle it like we do for 
BeanValidation and use messy reflection to isolate the dependency.
