----------------------------------

             Summary: NPE during FIND_MBRS when using shared transport
                 Key: JGRP-1862
                 URL: https://issues.jboss.org/browse/JGRP-1862
             Project: JGroups
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 3.5
            Reporter: Paul Ferraro
            Assignee: Bela Ban
            Priority: Blocker
             Fix For: 3.5


The following code within org.jgroups.protocols.TP.sendToSingleMember(...) throws an NPE if the transport is shared:

{code}
            Responses responses=(Responses)up(new Event(Event.FIND_MBRS, Arrays.asList(dest)));
            try {
                for(PingData data : responses) {
                    if(data.getAddress() != null && data.getAddress().equals(dest)) {
                        if((physical_dest=data.getPhysicalAddr()) != null) {
                            sendUnicast(physical_dest, buf, offset, length);
                            return;
                        }
                    }
                }
            }
            finally {
                responses.done();
            }
{code}

This is because up(Event) always returns null when using a shared transport.
