While Hibernate Search 5.1.1.Final was working fine for the purpose of Hibernate users, it was not compatible with the version of Infinispan Query currently included in WildFly (version 7.1.1.Final) as this was expected to strictly work with the Hibernate Search 5.0.x series.

This micro upgrade of Hibernate Search is therefore meant to restore binary compatibility with the integration point used by Infinispan Query.
