> Currently the SCR bundle only supports delayed components but not
> ServiceFactory components. That is the servicefactory attribute of the
> <service> element is in fact ignored. Another issue is, that for each bundle
> using a delayed component which is NOT a ServiceFactory a new instance of the
> component is created.
> Attaching a patch which solves the issues as follows:
> * Creates a new inner DelayedServiceFactoryServiceFactory (name is more
> functional than beautiful) class which supports for ServiceFactory
> components. Each call to the getService method creates a new instance of the
> component. The m_implementationObject is never set in this case. The
> ComponentContext used to call the activate method is kept in an map to use
> the same ComponentContext to call deactivate when the service is released
> through the ungetService method.
> * Modified DelayedComponentServiceFactory.getService method to return the
> m_implementationObject if not null. Otherwise the m_implementationObject is
> created, bound, activated and returned. The ungetService method is just
> enhanced with a comment indicating that the delayed component is only
> deactivated when the component is deactivated. The ComponentContext created
> by the getService method has the owner bundle field set to null as there is
> only really a single Component instance shared by all bundles.
> * Modified the invokeBindMethod and invokeUnbindMethods to take the object
> on which to call the method as a parameter. This accomodates for the
> DelayedServiceFactoryServiceFactory which never sets the
> m_implementationObject field.
