Vert.x HTTP/2 ALPN not available for JDK SSL/TLS engine

With Vert.x 3.4.2 and the runtime "io.netty:netty-tcnative-boringssl-static:2.0.5.Final" dependency, I get the following error:

SEVERE: ALPN not available for JDK SSL/TLS engine
io.vertx.core.VertxException: ALPN not available for JDK SSL/TLS engine

However, if I use the runtime "io.netty:netty-tcnative-boringssl-static:1.1.33.Fork26" dependency, no problem. Is this a Vert.x/Netty version compatability issue, or is something else at play?

You should make sure you always use the correct version of Netty tc-native with Vert.x.
