jboss-cli "java.lang.ArithmeticException: / by zero" when executed from /usr/bin/expect without tty --------------------------------------------------------------------------------------------------- Key: WFCORE-4278 URL: https://issues.jboss.org/browse/WFCORE-4278 Project: WildFly Core Issue Type: Bug Components: CLI Environment: Fedora 29, RHEL7.5 Reporter: Jean-Francois Denise Assignee: Jean-Francois Denise Priority: Major 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. {code} $ /usr/bin/expect expect1.1> spawn -nottycopy ./jboss-cli.sh spawn -nottycopy ./jboss-cli.sh 25901 expect1.2> interact You are disconnected at the moment. Type 'connect' to connect to the server or 'help' for the list of supported commands.
