> Currently any bundle wanting to contribute components has to implement an Activator extending the GenericActivator (or refer to the GenericActivator in
> the Manifest.MF. Additionally start/stop semantics of the SCR bundle are not implemented.
> Attached is a patch, which enhances the current Activator class as follows:
>    * On start load components of active bundles
>    * On stop unload all loaded components
>    * listen for bundle state changes to load/unload components:
>        * on BundleEvent.STARTED: Components are loaded
>        * on BundleEvent.STOPPING: Components are unloaded
> The BundleContext instance needed to load the Components is retrieved using the BundleImpl.getContext() method, which is accessed through reflection on the bundle instance.
> As a consequence of this patch, the GenericActivator class may be rebuilt into a proper component loader and need not be used as an activator for component bundles.
