[wildfly-dev] Using a custom module to preview "next-gen" Hibernate versions on WildFly 9

[Scott Marlow]

Hibernate ORM 5.0 doesn't work yet on WildFly.  Will push on this soon 
for WildFly 10.

This seems to be a bug.  I hit it a few days ago when I packaged 
Hibernate ORM 4.1.x with an application (in a unit test) and forgot to 
set the persistence provider in persistence.xml.

Providers are always found through the 
javax.persistence.spi.PersistenceProviderResolver, not directly from the 
deployment classpath.

Lets talk in a few days again on IRC.
