Konrad Windszus updated SLING-11677:
------------------------------------
Description:
When a servlet is registered with the OSGi HTTP Whiteboard pattern without the
property {{osgi.http.whiteboad.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!
