If I am using "karaf.framework=felix" all seems to be working. If I am using "karaf.framework=equinox" I got the reported error.
Here you could find a kar that demonstrate the problem: https://drive.google.com/file/d/0Bx99QXY8p6gvY3BoMXlZeXRIOWs/view?usp=sharing kar:install should write the above error message in your log. Installing the feature should trigger the error, too. You can extract the jar (javax.activation) of that kar and will see, that you are able to install it using bundle:install. -- View this message in context: http://karaf.922171.n3.nabble.com/4-0-0-M2-feature-install-system-bundle-tp4040561p4040562.html Sent from the Karaf - User mailing list archive at Nabble.com.
