[undertow-dev] HTTP/2 with undertow-core 1.2.6.Final?

[Michael Hixson]

The demo works perfectly for me locally - I see "h2" as the protocol.
I copy and paste the code from Http2Server.java into my own project,
run it, and I'm back to "http/1.1".  There has got to be something
going on in the pom's (or resource files or something) of the Undertow
example that I'm not seeing.

In any case I think it's pretty clear now that I'm screwing something
up.  I'll keep at it.
