I assume you mean the master (5.0) code base doesn't use Jandex but it 
looks like [2] in 4.3, is building/using the Jandex index.

How big of a change would it be to use Jandex (via 
"hibernate.jandex_index") in ORM 4.3/5.0 mapping?  Would be nice to have 
a comparison of how long it takes to deploy a large application with and 
without Jandex.
