Hello,
I tried the udp examples shipped with mina
(org.apache.mina.example.udp.perf). If i stop the UdpServer within the time
the client sending datagrams, the client(udp sender) get the following
exception:
java.net.PortUnreachableException

I wonder why it comes to such an exception as i thought the client would
just sending datagrams wether the receiver is alive or not? I wonder also
what the client is trying to
read from the socket?
Thanks,
Thomas
