[jira] [Created] (KARAF-4554) Completion of the 'watch' command hangs Karaf

J. Brébec created KARAF-4554:
--------------------------------

             Summary: Completion of the 'watch' command hangs Karaf
                 Key: KARAF-4554
                 URL: https://issues.apache.org/jira/browse/KARAF-4554
             Project: Karaf
          Issue Type: Bug
          Components: karaf-shell
    Affects Versions: 4.0.5
            Reporter: J. Brébec
            Priority: Critical


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.
