---------------------------------------

Hi Galder,
the actual test is here:
https://code.engineering.redhat.com/gerrit/gitweb?p=jdg-functional-tests.git;a=blob;f=remote/remote-client/src/test/java/com/jboss/datagrid/test/hotrod/HotRodRemoteCacheIT.java;h=e4f68d2ec83e732e14a0fba620964eea351ae09d;hb=HEAD

HR client is deployed into EAP sever from where it connects to ISPN server. When HR client libraries are bundled in war file, everything works fine. When HR client is moved into EAP modules and war file contains only test class (+ few other needed jars), HR clien is not able to unmarshall custom classes contained in war file (in test class). I don't remember the details, but obviously there's some class loading issue - probably modules use different classloader than one used for deployment (which makes sense for EAP as modules shouldn't depend deployed apps, but this is not the cases of HR client)

> Adding jar file with {{org.infinispan.server.test.client.hotrod.AbstractRemoteCacheIT$Person}} into jboss-deployment-structure as a module didn't helped.
