Galder Zamarreño commented on ISPN-4468:
----------------------------------------

Vojtech, what's the HR client being executed from? IOW, what kind of deployment is it running within? Looking at the test class I see no other deployments other than the filter/converter deployments, which are specific to HR event filter/converter tests. 

If the test class, and custom class are running as if they were in a JBoss module, they'd be some module hardwiring required to make this work. There's no way to get around that. On the contrary, if the test class and custom class are inside a WAR/EAR, the application server will do what it needs to do to make sure that the custom class is visible: https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7

Finally, rather than AbstractRemoteCacheIT, a test that's closer to what you are trying to do of marshalling a custom object is {{org.infinispan.test.integration.as.HotRodClientIT}}, where you have a remote HR client running within JBoss, using Infinispan Server modules which include HR client, hooked in Wildfly, and then have HotRodClientIT run inside a WAR in Wildfly. If you add a test to marshall custom classes there, it should work.
