Unable to start the JBoss EAP 6.4.x due to hibernate cache related error

Environment

• Red Hat JBoss Enterprise Application Platform (EAP)
  • 6.4.x

Issue

• After migrating the JBoss server from EAP 6.3.x (or earlier) to 6.4.x below exception is seen in server log file:

 Caused by: java.util.ServiceConfigurationError: org.infinispan.commands.module.ModuleCommandExtensions: Provider org.hibernate.cache.infinispan.util.CacheCommandExtensions not a subtype

Resolution

• This is a classloading related This content is not included.bug in the hibernate module in JBoss EAP 6.4.x.
  The issue is scheduled for the 6.4.9 CP release.

Workaround:

• Add an exclusion and dependency of org.hibernate module in jboss-deployment-structure.xml:

 <jboss-deployment-structure>
    <deployment>
       <exclusions>
           <module name="org.hibernate" />
       </exclusions>
       <dependencies>
           <module name="org.hibernate" />
       </dependencies>
    </deployment>
 </jboss-deployment-structure>

The same exclusion and dependencies element might need to be added to the inner subdeployment element as well.

    <sub-deployment name="some-inner-module.jar">
       <exclusions>
           <module name="org.hibernate" />
       </exclusions>
       <dependencies>
           <module name="org.hibernate" />
       </dependencies>
    </sub-deployment>

Root Cause

• The dependencies added automatically to a JPA application expose a META-INF/services file that conflicts with Infinispan/JDG packaged in the application.
