Description of problem:
Class loading issues for custom java classes when using remote listeners using modules

Version-Release number of selected component (if applicable): 6.5.1


How reproducible:


Steps to Reproduce:
1. Install jboss-datagrid-6.5.1-server, jboss-eap-6.4.0 and jboss-datagrid-6.5.1-eap-modules-remote-java-client.zip 
2. Start the servers 
3. Create a WAR project
4. Create a remote message listener like this:
@ClientListener
public class MessageListener {
	
	private Logger logger = Logger.getLogger(MessageListener.class);
	
	@Inject @MessageCache
	RemoteCache<String,Message> mc;
	
	@ClientCacheEntryCreated
	public void handleCreated(ClientCacheEntryCreatedEvent<String> e) {
		String key = e.getKey();
		logger.info(String.format("Recieved Cache Entry Created of event type %s", e.getType().toString()));
		Message message = mc.get(key); //LINE 29
		logger.info(String.format("Key is %s, value is %s", key,message.getText()));
	}
}
4. Compile and Deploy everything
5. Add entries to the cache.

Actual results:

Expected results:
A log message showing key and value of event


Additional info:
The exception is thrown because variable mc is null, e.g. CDI injection of the remote cache isn't not successful. One could probably work around the problem by not using CDI etc, but since the MessageListener is deploy as part of the WAR file this doesn't make sense to me.
