However I have no idea how to tell PlayAkkaHttp2Support to use 2.0.7 instead of 2.0.6. I tried adding the following to my build.sbt:
libraryDependencies += "org.mortbay.jetty.alpn" % "jetty-alpn-agent" % "2.0.7" % "provided"
The above doesn’t work as PlayAkkaHttp2Support configures its jetty agent as well and the two versions conflict. Does anyone know how to specify the jetty-apln-agent version?
