I have a cluster of 2 nodes with a WAR application deployed using web-console and exposing EJB remote business interface with following content:

@Stateless
@Remote
public class ServiceImplementation implements Service {

    @Resource( lookup = "java:jboss/clustering/group/ejb" )
    private Group channelGroup;

    @Override
    public void printNodeList() {
        for( Node node : channelGroup.getNodes()) {
            System.out.println( "node = " + node );
        }
    }
}

I invoke this EJB from a standalone client multiple times (to make sure that method calls will reach both nodes.)

The result is different on both nodes:

• On master node the result is correct = two nodes' names are printed out ,
• On second node the result is incorrect = no nodes' names are printed out.

This was working fine in WFLY 8.2.0.Final.
