      public void swappedService(org.osgi.framework.ServiceReference reference, Object service, org.osgi.framework.ServiceReference newReference, Object newService)
      Description copied from interface: ServiceTrackerCustomizer
      A service tracked by the ServiceTracker has an aspect service added or removed for a tracked service.

      This method is called when an aspect service has been either added or removed for a tracked service. This method will only be called when there's a new highest ranked service as result of adding or removal of the aspect service. In this case the previously highest ranked service is 'swapped' for the new highest ranked service ensuring the client always gets the highest ranked aspect.

      Specified by:
      swappedService in interface ServiceTrackerCustomizer
      Parameters:
      reference - The reference for the old highest ranked service.
      service - The service object for the old highest ranked service.
      newReference - The reference to the new highest ranked service.
      newService - The service object for the new highest ranked service.
