FWIW, those hooks in Hibernate 5 already exist, based on Jandex 1, of course :)

We are not currently using Jandex.  That was work happening under the metamodel redesign, which we had to push to 6.0.

When we do start using Jandex, the plan is to use the provided Jandex as a base.  But the problem always has been that Hibernate needs to augment that information from orm.xml.  Also we do have to manage cases outside of WildFly, so we'd have to build the Index manually.  Also, I want to look at the building of an index as a build-time step, storing some representation of that index into the artifact.  We can then locate that representation at runtime and load it via resource lookup, depending on what that saves/gains us perf wise (tbd).  Again this along with the passed Jandex index serve as the base index.  We at least still need to do that augmentation as Jandex does not handle that at all.

What is "end of deployment"?  Is that the end of phase-2 in our 2-phase JPA bootstrap design?  If so, that should be fine.

Best to talk with Jason but I heard that the Jandex indexes will soon be
larger (as part of the Java 8 changes).  As a result of the size
changes, Jandex indexes should only be accessed during the WildFly
deployment phases.

I'm not sure how Hibernate would use Jandex2 without creating its own
instances of the indexes, which would be expensive memory wise.

There is also the Hibernate 5.0 release, that we want to integrate with
WildFly.  I think that is where we might tightly couple Hibernate ORM
with Jandex, by passing a composite index into Hibernate.  The Jandex
reference will need to be cleared by the end of deployment.  Would that
help?

WildFly 9 builds off of WildFly 8’s Java EE7 support, and adds many new capabilities, including intelligent load balancing, HTTP/2 support, a new offline CLI mode, graceful single node shutdown, and a new Servlet-only distribution.
