Potentially Meaningless InterruptedIOException Can Be Logged Repeatedly
-----------------------------------------------------------------------

                 Key: JGRP-647
                 URL: http://jira.jboss.com/jira/browse/JGRP-647
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 2.6, 2.5.1, 2.5, 2.4.1 SP4, 2.4.1 SP3
            Reporter: Jimmy Wilson
         Assigned To: Bela Ban
            Priority: Minor
             Fix For: 2.4.2, 2.7


TP.down doesn't catch/handle the InterruptedIOException that can be thrown from the underlying send call when interrupted:

        try {
            if(use_outgoing_packet_handler)
                outgoing_queue.put(msg);
            else
                send(msg, dest, multicast);
        }
        catch(QueueClosedException closed_ex) {
        }
        catch(InterruptedException interruptedEx) {
        }
        catch(Throwable e) {
            if(log.isErrorEnabled()) {
                String dst=msg.getDest() == null? "null" : msg.getDest().toString();
                log.error("failed sending message to " + dst + " (" + msg.getLength() + " bytes)", e.getCause());
            }
        }

This can lead to it being logged repeatedly at the ERROR level:

2007-11-14 10:02:30,040 ERROR -> (PingSender) [UDP] failed sending message to null (0 bytes)

2.5/2.6 don't handle the InterruptedIOException either, but since this was reported with EAP 4.2 (JGroups 2.4.1.SP3), I 'd like to see it in 2.4.2 if possible.  That way, it can make it into a 4.2/4.3 EAP CP.
