             Summary: COUNTER does not work with ForkChannel on an already connected main channel
                 Key: JGRP-2156
                 URL: https://issues.jboss.org/browse/JGRP-2156
             Project: JGroups
          Issue Type: Bug
            Reporter: Bela Ban
            Assignee: Bela Ban
             Fix For: 4.0, 3.6.13


The following code doesn't work:
{code:java}
JChannel ch=new JChannel().connect("cluster");
ForkChannel fc=new ForkChannel(ch, "counter-stack", "counter-channel", true,
                                       ProtocolStack.Position.ABOVE, FRAG2.class,
                                       new COUNTER());
CounterService counter_service=new CounterService(fc);
fc.connect("ignore");
Counter counter=counter_service.getOrCreateCounter("cntr", 0);
{code}

Method {{getOrCreateCounter()}} hangs as its coord is null because it didn't get a view change. The issue is that COUNTER only processes view changes sent from below but not from above. The former happens when the main channel is connected, the latter when ForkChannel.connect() is called.

SOLUTION: add view change processing in down().
