Motivation:
DelegatingSslContext at the moment intercept newEngine calls and allow to init the SslEngine after it is created. The problem here is that this may not work the SSLEngine that is wrapped in the SslHandler when calling newHandler(...). This is because some SslContext implementations not delegate to newEngine(...) when creating the SslHandler to allow some optimizations. For this we should also allow to init the SslHandler after its creation and by default just delegate to initEngine(...).
Modifications:
Allow the user to also init the SslHandler after creation while by default init its SSLEngine after creation.
Result:
More flexible and correct code.
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.
