Seth Leger commented on KARAF-5251:
-----------------------------------
Should this be a part of the default Karaf distro? JNA 4.3.0 is already part of
the Karaf distro in support of systemd integration:
{noformat}
# tar ztf apache-karaf-4.1.1.tar.gz | grep jna
apache-karaf-4.1.1/system/net/java/dev/jna/
apache-karaf-4.1.1/system/net/java/dev/jna/jna/
apache-karaf-4.1.1/system/net/java/dev/jna/jna/4.3.0/
apache-karaf-4.1.1/system/net/java/dev/jna/jna/4.3.0/jna-4.3.0.jar
apache-karaf-4.1.1/system/net/java/dev/jna/jna-platform/
apache-karaf-4.1.1/system/net/java/dev/jna/jna-platform/4.3.0/
apache-karaf-4.1.1/system/net/java/dev/jna/jna-platform/4.3.0/jna-platform-4.3.0.jar
apache-karaf-4.1.1/lib/boot/jna-platform-4.3.0.jar
apache-karaf-4.1.1/lib/boot/jna-4.3.0.jar
{noformat}
Otherwise features that worked fine on Karaf 4.0 and lower stop working on 4.1
because of this side-effect.

> 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:
> {noformat}
> karaf@root()> feature:install java-native-access
> Error executing command: java.lang.InterruptedException

> 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.
> Error in initialization script:
> /root/Downloads/apache-karaf-4.1.1/etc/shell.init.script: Task
> java.util.concurrent.FutureTask@3c8bdda9 rejected from
> java.util.concurrent.ThreadPoolExecutor@7989445c[Terminated, pool size = 0,
> active threads = 0, queued tasks = 0, completed tasks = 0]
> 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.
