------------------------------------

             Summary: StringIndexOutOfBoundsException in ShellTable
                 Key: KARAF-7580
                 URL: https://issues.apache.org/jira/browse/KARAF-7580
             Project: Karaf
          Issue Type: Improvement
    Affects Versions: 4.4.1, 4.3.7
            Reporter: Rico Neubauer


Karaf commands that provide text with line breaks in their description can break the general {{help}} command and lead to exception below.

This line seems to be missing a check for st2.length:

Will link a pull-request.
