I recently stumbled over DependencyManager and immediately found it very nice to work with. I have some cases where I instantiate my own DependencyManagers (ex. one per monitored bundle in a SynchronousBundleListener). Now that I found myself copy/pasting a method that removes all components from a DependencyManager, I modified DM to add a clear() method on DependencyManager. Basically I moved the code from DependencyActivatorBase. I hope you find this patch useful.
