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.

How to build
For the detailed information about building and developing Netty, please visit the developer guide. This page only gives very basic information.
You require the following to build Netty:
- Latest stable Oracle JDK 7
- Latest stable Apache Maven
- If you are on Linux, you need additional development packages installed on your system, because you'll build the native transport.
Note that this is build-time requirement. JDK 5 (for 3.x) or 6 (for 4.0+) is enough to run your Netty-based application.
Branches to look
The 'master' branch is where the development of the latest major version lives on. The development of all other versions takes place in each branch whose name is identical to <majorVersion>.<minorVersion>. For example, the development of 3.9 and 4.0 resides in the branch '3.9' and the branch '4.0' respectively.
