You must be doing something wrong.
I added this small bit of code to one of karaf's activators:
bundleContext.getBundle(0).getBundleContext().addBundleListener(new
SynchronousBundleListener() {
@Override
public void bundleChanged(BundleEvent event) {
System.out.println(event);
}
});
Here's the output when stopping under equinox:
*karaf*@root()> ($.context bundle 0) stop 1
