    Description

      Running the jboss-cli.sh from expect without tty (e.g. a cron or a jenkins job), causes a division by zero. (you can simulate non-availability of the real tty with "-nottycopy" :

      NB: The failure occurs when you type a character in the CLI console.

      $ /usr/bin/expect
expect1.1> spawn -nottycopy ./jboss-cli.sh
spawn -nottycopy ./jboss-cli.sh
