> PreferencesManager#bundleChanged tries to intercept bundles that are uninstalled. However, if the PreferencesManager itself is stopped, it does not unregister itself as bundle listener, causing possible NPEs when other bundles depending on the preferences service are stopped later on, for example during a shutdown.
> I've got a patch available, will attach it to this issue to be applied.
