We can upgrade to Hibernate Search 5.10.0.Final to benefit the Infinispan Query component.

However, this is much easier if combined with the upgrade to Hibernate ORM 5.3.0.Final as integration tests would not need to diverge (JPA 2.2).

Both these versions are included in WildFly 13. WildFly 13.0.0.Beta1 is available now so switching to this version to run integration test of the Lucene Directory Modules already makes sense - as Infinispan no longer ships a dependency to a specific WildFly version: this is used only for integration tests.
