Motivation: When a datagram packet is sent to a destination where nobody actually listens to, the server O/S will respond with an ICMP Port Unreachable packet. The ICMP Port Unreachable packet is translated into PortUnreachableException by JDK. PortUnreachableException is not a harmful exception that prevents a user from sending a datagram. Therefore, we should not close a datagram channel when PortUnreachableException is caught. Modifications: - Do not close a channel when the caught exception is PortUnreachableException. Result: A datagram channel is not closed unexpectedly anymore. |
