Enabling Vaadin push on Karaf needed a newer Jetty server. Vaadin push depends on Atmosphere runtime 2.4.11.vaadin2 which needs at least Jetty 9.3.19.v20170502 instead of the 9.3.15.v20161220 that lacks the constructor WebSocketServerFactory(ServletContext, policy) in class org.eclipse.jetty.websocket.server.WebSocketServerFactory.
I upgraded to Jetty 9.3.21.v20170918 and added the missing import-package declaration javax.servlet.annotation; version="[2.3.0,4.0.0)" to pax-web-extender-whiteboard.
This allows annotations like @WebInitParamto to be parsed.
