Hi, Did we change Hibernate to automatically enhance/rewrite application entity classes by default? I remember hearing a few times that we would but don't remember if that happened. This is related to WildFly jira WFLY-8858 [1], which I'm not yet sure of how to completely fix (involves deal with multiple deployment ordering problems with application level datasources, CDI beanmanagers, parallel application deployment and application entity class enhancement). One WildFly issue is that the application datasources aren't available until late in WildFly deployment but the JPA container needs to register the JPA classloader level transformers very early, so Hibernate can rewrite application classes. This is further complicated by our WildFly CDI implementation needing to read application class definitions. I wonder if it could make sense for org.hibernate.jpa.boot.spi.EntityManagerFactoryBuilder to have a separate way to register the ClassTransformer transformer early and trigger the PU bootstrap on the first call to registered ClassTransformer's. If that doesn't happen, then we defer bootstrap until EntityManagerFactoryBuilder.build() is called.

Knowing the answer to that, will help answer my question above.
