Motivation: If an event occurs which generates non-application data (shutdown, handshake failure, alert generation, etc...) and the non-application buffer in the ByteBuffer BIO is full (or sufficiently small) we may not propagate all data to our peer before tearing down the socket. Modifications: - when wrap() detects the outbound is closed, but there is more data pending in the non-application buffers, we must also check if OpenSSL will generate more data from calling SSL_shutdown again - when wrap() detects a handshakeExcpetion during failure we should check if OpenSSL has any pending data (in addition to the non-application buff) before throwing the handshake exception Result: OpenSslEngine more reliably transmits data to the peer before closing the socket.

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.
