NPE from FacesServlet on page load #1

This has to do with ServletContext#getNamedDispatcher, which may be stubbed out currently.

The trouble is more that it's looking for "Designer Resource Servlet", which isn't loaded. We could either load it as a true servlet in the Jetty config or wrap around this.

I haven't seen this in a bit, so it may have been fixed by another change.
