Motivation: At the moment we use SSL.getLastError() in unwrap(...) to check for error. This is very inefficient as it creates a new String for each check and we also use a String.startsWith(...) to detect if there was an error we need to handle. Modifications: Use SSL.getLastErrorNumber() to detect if we need to handle an error, as this only returns a long and so no String creation happens. Also the detection is much cheaper as we can now only compare longs. Once an error is detected the lately SSL.getErrorString(long) is used to conver the error number to a String and include it in log and exception message. Result: Performance improvements in OpenSslEngine.unwrap(...) due less object allocation and also faster comparations.

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.
