      Description

      $ sudo "/usr/lib/jvm/java-1.8.0/bin/java" -jar "/tmp/kitchen/cache/jenkins-cli.jar" -s http://aws-instance:8080 -i "/tmp/kitchen/cache/jenkins-key" restart
      
      ERROR: Unexpected exception occurred while performing restart command.
      java.lang.NullPointerException

      The server has "StaplerResponse rsp == null".

      The issue does not appear with safe-restart, as nullity is checked on all variables

            Probably harmless, as the restart has already been initiated, but would cause the noise and incorrect exit status on the command.

            To fix, prepend the original

            if (rsp != null) // null for CLI
