The key Servlet 4 specification slated to be included in Java EE 8 continues to make progress and just released its first early draft review (EDR). You can download and take a look at the draft from the JCP site. Bringing HTTP/2 support to server-side Java is the principal goal of Servlet 4. Specification lead Ed Burns has an excellent slide deck covering HTTP/2 and Servlet 4 at a high level (click here if you can't see the embedded slide deck):
There are many ways for you to get involved or just send feedback as always and this is a great point to do so. You are always welcome to join the expert group proper via the JCP page for the specification. You can always simply join the discussion by subscribing to the Servlet 4 specification user alias. If you would rather participate as a group through your JUG you can do that easily via Adopt-a-JSR.
