Okay, so I think the root of the issue is detailed in this blog post [1].
When I tested using Chromium on Ubuntu, NPN and SPDY were still
supported and it worked. But testing with Chrome (version 51), The
client, over ALPN, only supports HTTP/1.1 and HTTP/2.
Grizzly's HTTP/2 support is still in development, and this information
is a good reason to put more time into it.
