---------------------------------
Summary: Installing a feature containing JNA refreshes many system
bundles
Key: KARAF-5251
URL: https://issues.apache.org/jira/browse/KARAF-5251
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}
Import-Package =
com.sun.jna;resolution:=optional,
com.sun.jna.ptr;resolution:=optional,
com.sun.jna.win32;resolution:=optional,
...
{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:

Apache Karaf (4.1.1)
Hit '<tab>' for a list of available commands
and '[cmd] --help' for help on a specific command.
Hit '<ctrl-d>' or type 'system:shutdown' or 'logout' to shutdown Karaf.

This problem can be reproduced by creating a feature containing the {{jna}} and
{{jna-platform}} bundles and installing it on a fresh Karaf instance.
