> 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.
> The same issue affects org.jgroups.protocols.TP.fetchPhysicalAddrs(...):
> {code}
>     if(!missing.isEmpty()) {
>         Responses rsps=(Responses)up(new Event(Event.FIND_MBRS, missing));
>         rsps.done();
>     }
> {code}
