Did you also add a bundle which prevents stopping ? PS: in your traces which event is the shutdown itself?

This may fail to happen when (at least) a bundle does not end. So I added a watchdog which exits Java when a time limit has been exceeded (note: maybe there is already a way to do so - ?). The way I coded it does not work when the shutdown is made via the Karaf prompt, so I decided to enhance it. Googling “Karaf shutdown hook”, I found an old thread talking about SynchronousBundleListener. The issue I’m facing is that I get no event when performing bundle0.stop(Bundle.STOP_TRANSIENT) and one of the bundles refuses to stop. The listener is registered via bundle0.getBundleContext().addBundleListener(new SynchronousBundleListener() { … }). Is it normal? How to force Karaf to shutdown?
