I also had similar issues, while trying to update the feature by simply replacing the older artifacts with the new one (situated in the same location [I was using file system to install feature bundles]).
Thus, I found that upgrading features with a newer version was an easier and better option. Somehow they were cached, and did not refresh the state of the new artifacts. -- Sent from: http://karaf.922171.n3.nabble.com/Karaf-User-f930749.html
