Damian Golda commented on PAXWEBEX-28:
--------------------------------------
I found, that while stopping bundle, HttpServiceFactoryImpl.ungetService is
called but HttpServiceTracker is NOT notified that HttpService is unregistered
(no removedService call).
So HttpServiceTracker doesn't notify listeners that means WebApplication and
WebApplication still keeps reference to HttpService which actually is
HttpServiceProxy to HttpServiceStopped.
When I start my bundle again, the same WebApplication is used and pax web
whiteboard try to register servlet in HttpServiceStopped which fails.
> Stop and start for bundle with servlet gets Http service has already been
> stopped
