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

[Michael Hixson]

Hi Jason,

I think so.

  $ java -version
  java version "1.8.0_45"
  Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
  Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)

I just remembered I also installed the JCE Unlimited Strength thing.
Not sure if that would interfere.

I'll retry with a fresh JDK.  Since you confirmed it's supposed to
work, I'll also try to come up with minimal shareable code that's not
working for me.
