Jean-Baptiste Onofré commented on KARAF-3217:
---------------------------------------------
[~ericlilja] it's because the {{scr:list}} you used was NOT the Felix SCR one,
but one provided by Karaf:
[https://github.com/apache/karaf/blob/karaf-4.1.2/scr/command/src/main/java/org/apache/karaf/scr/command/action/ListAction.java]
This {{scr:list}} command supported {{-s}} or {{--show-hidden}} option.
I removed the Karaf SCR command to use the one provided by Felix SCR directly
(to avoid confusion for users and Felix SCR commands are more complete than the
single one we have in Karaf).
So, you got my point now: using Felix SCR commands, we will have the
{{IllegalArgumentException: coerce}} if you don't provide the right arguments
list to a command.
A possible solution is to exclude the Felix SCR command and provides Karaf SCR
commands (using the Karaf style, including help generation, etc).
