In fact I guess that’s the problem, the event seems not to be fired before stopping bundles.
When all bundles react normally, i.e. they stop, I get the stopping event. When at least one does not stop as expected, then I get no stopping event. Would you be kind enough to try again with a non-stopping-bundle and displaying the event type?

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?
