Hello
In theory - yes, it does support HTTP/2.
In practice - also yes, because I see pax-web-jetty before version 8 indeed tries to instantiate `org.eclipse.jetty.http2.server.HTTP2ServerConnectionFactory` and use it as an argument to `org.eclipse.jetty.server.AbstractConnector#addConnectionFactory()`.
But in real practice - there are no integration tests in Pax Web that ensure this is correct handling and what's more important (at least for me) - that it's consistent across pax-web-jetty, pax-web-tomcat and pax-web-undertow.
In Pax Web 8 I'm going to add real integration tests (including for example HTTP/2 over clear text), but it's not ready yet.
regards
