> Situation:
> # A ServletRequestListener registered with the Http Whiteboard Service (standard OSGi
Http Whiteboard) with property {{osgi.http.whiteboard.listener==true}}.
> # A Servlet registered with the traditional OSGi HttpService
> Problem: The ServletRequestListener is not called for requests for requests to said servlet.
> Investigation: It looks like the ServletRequestListenerManager used to handle ServletRequestListener
services for traditionally registered Servlets explicitly ignores listeners registered with
the {{osgi.http.whiteboard.listener}} property set. See this code in [ServletRequestListenerManager|https://github.com/apache/felix/blob/trunk/http/base/src/main/java/org/apache/felix/http/base/internal/service/listener/ServletRequestListenerManager.java#L45].
> For one thing, the listener should at best ignore services registered with the property
set to true. If the property is set to anything else, it will explicitly be ignored by the
OSGi Whiteboard Http Service and thus should probably be accepted by the legacy Felix Http
Service implementation.
> On the other hand: Why ignore at all ? Originally the legacy Felix Http Service accepted
all Servlet API listeners regardless of such property set. So if there is a listener used
and the Jetty bundle is updated and the service updated to make sure it is called for new
OSGi Whiteboard services it will not be called any more for the legacy registered services
> I think the legacy Felix Http Service should just accept all listeners like it always
did.
