             Summary: NPE in Http2PriorityTree$Http2PriorityNode.addDependent
                 Key: WFLY-6688
                 URL: https://issues.jboss.org/browse/WFLY-6688
             Project: WildFly
          Issue Type: Bug
          Components: Web (Undertow)
    Affects Versions: 10.0.0.Final
            Reporter: Juergen Zimmermann
            Assignee: Stuart Douglas


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.

{{ERROR [org.xnio.listener] XNIO001007: A channel event listener threw an exception: java.lang.NullPointerException
