Christian Schneider commented on KARAF-5144:
--------------------------------------------
Can you provide exact steps to reproduce this? Also your system might be
important.
Normally $.jline.terminal does not resolve to null.
I think this is where the exception is caused:
max_colors = ($.jline.terminal getNumericCapability max_colors)
I think we can solve this in two ways. Either we make sure .jline.terminal is
never null or we check for null in the script.
> java.lang.RuntimeException: Command name evaluates to null: $.jline.terminal

> Key: KARAF-5144
> URL: https://issues.apache.org/jira/browse/KARAF-5144
> Project: Karaf
> Issue Type: Bug
> Components: karaf-shell
> Affects Versions: 4.1.1
> Reporter: Roland Hauser
> Assignee: Jean-Baptiste Onofré
> Fix For: 4.2.0, 4.1.2
>
>
> Method executeScript on class org.apache.karaf.shell.ssh.ShellCommand throws
> (and catches) this exception, when property karaf.shell.init.script in
> system.properties is set to "karaf.shell.init.script = etc/shell.init.script"
> to avoid KARAF-5143. This means that currently no command can be executed
> which is specified in the shell init-script, which makes it impossible for us
> to deploy our application on Karaf 4.1.1.
