The extensions are loaded by the Infinispan Core jar, so that's the one I'd assume needs to see the Hibernate Infinispan 2LC jar

However, I think that I need to know which jar expects to see the ModuleCommandExtensions.  I think your telling me below, that Infinispan needs to see these, but I want to make sure.
