Hey,

are you using proper version of apln-boot jar that applies to your exact version of jdk?

Since 10.1, WildFly itself doesn't use the apln-boot hack anymore since, but uses different solution in undertow that doesn't require patching jdk classes.

Hello undertow-dev,

I'm trying to use WildFly to send a push notification to iOS devices, which requires the use of HTTP/2. Using OkHttp (http://square.github.io/okhttp/), I was able to send a request successfully in an external java project using the JVM option: -Xbootclasspath/p:<path-to-alpn-boot-jar>.

After checking the documentation here: http://undertow.io/blog/2015/03/26/HTTP2-In-Wildfly.html, I was unable to do the same in WildFly. When I run the server I get:

okhttp3.OkHttpClient -- ALPN callback dropped: SPDY and HTTP/2 are disabled. Is alpn-boot on the boot class path?

which leads me to think that it is not actually on the classpath. I have the same configuration as that in the blog post, except having Wildfly 10.0.1.Final instead of Wildfly 9.0.0.Beta1. I have the correct alpn-boot jar version since it already works outside of WildFly, but I do not know what else I could be missing. Thank you very much for your time.

Best,
Hanan
