Description

During initialization of a bundle, it is possible to encounter a race condition in which the BundleTrackerCustomizer::addingBundle(Bundle bundle, BundleEvent event) is triggered after the bundle has begun initialization of a immediate component.

@Component(immediate = true)
@Service
public class ExampleImpl {

    @Activate
    public void activate(ComponentContext context) {
        Resource resource = ....
        // Race condition possible here... Could be executed before the BundleTracker (ModelPackageBundleListener)
        SlingModelExample example = resource.adaptTo(SlingModelExample);
    }

}
