[infinispan-issues] [JBoss JIRA] (ISPN-4468) HR client is not able to unmarshall custom class when using AS modules

[Vojtech Juranek (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-4468?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12981098#comment-12981098 ] 

Vojtech Juranek commented on ISPN-4468:
---------------------------------------

Do we want the users to touch module dependencies? IMHO the marshaller classloader should be able to load classes from deployment and in the worst case from jboss-deployment-structure.xml. I tried to redefined infinispan.commons module to depend on my custom class in jboss-deployment-structure.xml, but this doesn't work as well.
