With other Java EE 8 tech previews we handle it by loading the correct resource based on a system property. Is this not possible with Hibernate for some reason? For example have a look at the javax.validation.api module [1].

Is there a need to create a new module?

Yes, WildFly needs to keep including the current Hibernate ORM 5.1 jar for application compatibility but we also need to include the newer Hibernate ORM 5.3+ jar for EE 8/JPA 2.2 use. So, we really need a new ORM module, since we will keep both Hibernate versions in WildFly for a while (ORM 5.3 may get swapped out with a newer version later, TBD).
