You have 2 events for each bundle (but for the system bundle, the first event which is a STOPPING event). For each of those 2 events, the first one is a STOPPING, then the framework calls the activator stop, then fire a STOPPED event.
Are you sure you're using activators ? because the problem may be completely different if using a blueprint extender and a blueprint event that does not stop. In that case, what happens is that the blueprint extender intercepts the STOPPING event from the system bundle and preemptively shutdown all blueprint bundles in an orderly fashion. This usually helps by choosing a better stopping order than the default one, depending on service used between bundles. The problem is that given the extender stops the blueprint bundles preemptively, the bundles will be stopped before the framework has a change to send the STOPPING event for the bundle. It's actually the same as if you would stop the blueprint extender in a running framework: all blueprint containers will be destroyed, but the lifecycle of the bundles would not be affected. This behavior can be turned off by using org.apache.aries.blueprint.preemptiveShutdown=false in the etc/config.properties file. 2016-11-18 16:49 GMT+01:00 CLEMENT Jean-Philippe < jean-philippe.clem...@fr.thalesgroup.com>: > 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? > > > > Regards, > > JP > > > > *De :* Guillaume Nodet [mailto:gno...@apache.org] > *Envoyé :* vendredi 18 novembre 2016 16:40 > > *À :* user > *Objet :* Re: Karaf shutdown > > > > > > > > 2016-11-18 15:01 GMT+01:00 CLEMENT Jean-Philippe < > jean-philippe.clem...@fr.thalesgroup.com>: > > Did you also add a bundle which prevents stopping ? > > > > No, but the first event is sent before actually stopping any bundle. > > > > > > PS: in your traces which event is the shutdown itself? > > > > It's not, because I paste a wrong output. > > Here's the full output, and the interesting event is the first one.
