Juergen Zimmermann commented on WFLY-6688:
------------------------------------------

[~swd847], [~ctomc] Just for completeness: I manually upgraded to 1.3.21 which is used in WFLY Core 2.2.0.CR2, and the issue is gone.

> I'm using Windows 8.1 with JDK 8u92, WildFly 10.0.0.Final (Undertow 1.3.15) and alpn-boot 8.1.8.v20160420. When accessing any JSF-based web page (via Chrome) I get the following stacktrace. The REST clients are not using HTTP/2 and work fine.
