I think the import package of org.osgi.framework.launch came from the AriesBundleTrackerCustomizer in util package, as the blueprint extender uses it optionally, when detecting the existence of composite bundle factory service.
So it should be optional transitive dependency for blueprint, while it is currently marked as required, which is incorrect. Does this sound right?
