[hibernate-dev] HHH-8076 - CDI-capable entity listeners

[Sanne Grinovero]

I checked :
 - Hibernate OGM
 - Hibernate Search
 - Hibernate Validator
 - WildFly

And none are using the listeners you listed. In the case of WildFly, I
don't know of course about all the frameworks which are included in
there.
