Motivation: For applications that set their own logger factory, they want that logger factory to be the one logger factory. Yet, Netty eagerly initializes this and then triggers initialization of other classes before the application has had a chance to set its preferred logger factory. Modifications: With this commit there are two key changes: - Netty does not attempt to eagerly initialize the default logger factory, only doing so if the application layer above Netty has not already set a logger factory - do not eagerly initialize unrelated classes from the logger factory; while the motivation behind this was to initialize ThreadLocalRandom as soon as possible in case it has to block reading from /dev/random, this can be worked around for applications where it is problematic by setting securerandom.source=file:/dev/urandom in their Java system security policy (no, it is not less secure; do not even get me started on myths about /dev/random) Result: Netty uses the logger factory that the application prefers, and does not initialize unrelated classes.

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
Development of all 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.
