FTR: The default context created by the Http Service OTOH has a default ranking
of "0"
(https://docs.osgi.org/specification/osgi.cmpn/7.0.0/service.http.html#d0e7040),
that leads me to believe that the service ranking of "default" of HTTP
Whiteboard Service is just plain wrong. !HTTP-Service-Default-Context.png!

> When a servlet is registered with the OSGi HTTP Whiteboard pattern without
> the property {{osgi.http.whiteboard.context.select}} the "default" context
> helper is used
> (https://docs.osgi.org/specification/osgi.cmpn/7.0.0/service.http.whiteboard.html#service.http.whiteboard.common.properties)
> With the Jetty Implementation from Felix in Sling this has the
> {{service.ranking}} {{Integer.MIN_VALUE}} while the one for the default Sling
> Main Servlet has no explicit ranking (i.e. 0). That leads to the fact that
> the Sling Main servlet always takes precedence as
> {quote}
> In the case of two Servlet Context Helpers with the same path, the service
> with the highest ranking is searched first for a match. In the case of a tie,
> the lowest service ID is searched first.
> {quote}
> (https://docs.osgi.org/specification/osgi.cmpn/7.0.0/service.http.whiteboard.html#service.http.whiteboard.servletcontext)
> as both "default" and "org.apache.sling" are registered for path "<root>".
> The Sling Main servlet context should use a lower ranking so that simple
> servlets registered via OSGI HTTP Whiteboard pattern without explicit context
> can kick in at all!
