We can workaround this issue by now when we remove following lines from the=
 shell.init.script:

{code}
prompt =3D "^[[1m${USER}^[[0m@${APPLICATION}(${SUBSHELL})> "

__load_class =3D {
  (($.reader class) classLoader) loadClass $1
}

# On 256 colors terminal, add a right prompt
max_colors =3D ($.jline.terminal getNumericCapability max_colors)
if { %(max_colors >=3D 256) } {
  __rprompt_formatter =3D (((__load_class java.text.SimpleDateFormat) getCo=
nstructor (__load_class java.lang.String)) newInstance \'$'\u001B\[90m'\'HH=
:mm:ss)
  __date_class =3D (__load_class java.util.Date)
  \#rprompt =3D { $__rprompt_formatter format ($__date_class newInstance) }
}

setopt group
keymap "^[OA" up-line-or-search
keymap "^[OB" down-line-or-search

>          Components: karaf-shell
>    Affects Versions: 4.1.1
>            Reporter: Roland Hauser

> Method executeScript on class org.apache.karaf.shell.ssh.ShellCommand thr=
ows (and catches) this exception, when property karaf.shell.init.script in =
system.properties is set to "karaf.shell.init.script =3D etc/shell.init.scr=
ipt" to avoid KARAF-5143. This means that currently no command can be execu=
ted which is specified in the shell init-script, which makes it impossible =
for us to deploy our application on Karaf 4.1.1.
