Minor Description
Dropping a kar file in the deploy folder doesn't work.
For instance, if we try the hotdeployment of the my-kar.kar file provided in the demos, we can see the kar file considered by the kar deployer and we can see it with the kar:list command:
karaf@root()> kar:list KAR Name --------------------- my-kar-4.0.0-SNAPSHOT
However, the kar file is not effectively deployed, as Karaf tries the resolve the features XML on remote Maven repo instead of using the kar content:
