Description

In the shell, write "watch " followed by the <tab> key : Karaf hangs and take 100% cpu.

The 'CommandsCompleter' used in the 'WatchAction' add itself to the list of known completers, resulting in an infinite list of possible commands.

I put the priority on critical on this issue, because it's really easy to kill a container in production with this command.
