Jean-Baptiste Onofré resolved KARAF-5251.
-----------------------------------------
    Resolution: Not A Problem

I would say that you should install JNA bundle as start bundle (in {{etc/startup.properties}}).

>             Project: Karaf
>          Issue Type: Bug
>          Components: karaf-shell
>    Affects Versions: 4.1.0
>            Reporter: Seth Leger
>            Priority: Critical

> jline 3.X that is included with the shell in Karaf 4.1+ has an optional dependency on the Java Native Access packages.

> ...
> {noformat}
> This means that if you install a feature that includes the JNA bundles, it will refresh the jline bundle and all related bundles to satisfy this dependency. The group of related bundles that gets refreshed seems to be very large and can have a variety of negative side-effects:
> - Terminating the current SSH session
> - Terminating subsequent feature installations
> - The {{shell.init.script}} seems to get interrupted as it refreshes, printing a lot of error messages:
> {noformat}
> karaf@root()> feature:install java-native-access 
> Error executing command: java.lang.InterruptedException

> Error in initialization script: /root/Downloads/apache-karaf-4.1.1/etc/scripts/shell.completion.script: null
> {noformat}
> This problem can be reproduced by creating a feature containing the {{jna}} and {{jna-platform}} bundles and installing it on a fresh Karaf instance.
