      I am trying to create a ForkChannel based on the example in docs with code, when FORK protocol not present in the main stack

              channel=new JChannel("tcp.xml"));
        channel.connect("RpcDispatcherTestGroup");        
        ForkChannel forkChannel = new ForkChannel(channel, "test-rpc", name, true, ProtocolStack.BELOW, FRAG2.class);
        forkChannel.connect("test-rpc");

      this ends with 

      Exception in thread "main" java.lang.NullPointerException
	at org.jgroups.protocols.FORK.createForkStack(FORK.java:199)
	at org.jgroups.fork.ForkChannel.<init>(ForkChannel.java:79)
	at org.teiid.systemmodel.RpcDispatcherTest.start(RpcDispatcherTest.java:32)
	at org.teiid.systemmodel.RpcDispatcherTest.main(RpcDispatcherTest.java:54
