Related: #3797 Motivation: There is a race condition where DnsNameResolver.query() can attempt to increase the reference count of the DNS response which was released already by other thread. Modifications: - Make DnsCacheEntry a top-level class for clear access control - Use 'synchronized' to avoid the race condition - Add DnsCacheEntry.retainedResponse() to make sure that the response is never released while it is retained - Make retainedResponse() return null when the response has been released already, so that DnsNameResolver.query() knows that the cached entry has been released Result: The forementioned race condition has been fixed.

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.
