Michael Mangeng commented on KARAF-3593:
----------------------------------------
Oh and i forgot to mention: This does NOT happen if i simply deploy the plugin
into the "deploy" directory when the instance is already running. It occurs
only if i startup an instance (e.g. instance:start test) and all bundles are in
the deploy directory already and the instance was started up before.
