This exception is displayed on windows because the socket is closed (see
qpid-1251 for more details). I would suggest the following fix:
add the following catch clause to method run() of class
org.apache.qpid.transport.network.io.IoReceiver
catch (SocketException se)
{
if( ! (se.getMessage().equalsIgnoreCase("socket closed") &&
closed.get()))
{
receiver.exception(se);
}
}
This would swallow socket closed exception when the connection has previously
been closed
