> When upgrading from karaf-4.0.7 to karaf-4.1.1 we are seeing several NPE exceptions in the log related to Activator handling BundleEvent.UNRESOLVED before BundleEvent.RESOLVED events are recieved. This results in a NPE in StoredWiringResolver.delete(...) since the wiring map doesn't contain the bundleId.
