Hi Achim
1. I am not really understand what wrapper.on_exit.default=RESTART
does, but with wrapper.on_exit.99=RESTART, and If can get my bundle to
shutdown karaf with exit code 99. That would be test.
2. Our usage of karaf is having a feature ( with a bunch of bundles
it has many classes 200+ and growing ). We remotely access karaf via
JMX to update our feature feature by having karaf to contact maven
repo to pickup the update.
How often do we do the update? quite often during development.
But not expect a lots once it get to customer size. This is how we
deliver bug fix and added feature.
Thanks
-Dan
