Motivation: As reported in #4402, the FastThreadLocalBenchmark shows that the JDK ThreadLocal is actually faster than Netty's custom thread local implementation. I was looking forward to doing some deep digging, but got disappointed :(. Modifications: The microbenchmark was not using FastThreadLocalThreads and would thus always hit the slow path. I updated the JMH command line flags, so that FastThreadLocalThreads would be used. Result: FastThreadLocalBenchmark shows FastThreadLocal to be faster than JDK's ThreadLocal implementation, by about 56% in this particular benchmark. Run on OSX El Capitan with OpenJDK 1.8u60.

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.
