Motiviation: DefaultChannelId attempts to acquire a default process ID by determining the process PID. However, to do this it attempts to punch through to the system classloader, a permission that in the face of a restrictive security manager is unlikely to be granted. Looking past this, it then attempts to load a declared method off a reflectively loaded class, another permission that is not likely to be granted in the face of a restrictive security manager. However, neither of these permissions are necessary as the punching through to the system security manager is completely unneeded, and there is no need to load a public method as a declared method. Modifications: Instead of punching through to the system classloader requiring restricted permissions, we can just use current classloader. To address the access declared method permission, we instead just reflectively obtain the desired public method via Class#getMethod. Result: Acquiring the default process ID from the PID will succeed without requiring the runtime permissions "getClassLoader" and "accessDeclaredMembers".

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.
