Embedded host-controller throws NPE on regular shutdown ------------------------------------------------------- Key: WFCORE-931 URL: https://issues.jboss.org/browse/WFCORE-931 Project: WildFly Core Issue Type: Bug Components: CLI, Domain Management Affects Versions: 2.0.0.Beta4 Reporter: Petr Kremensky Assignee: Tomas Hofman Invoking the /host=master:shutdown operation on embedded host-controller gives me NPE. *Standalone* {noformat} [standalone@embedded /] shutdown The command is not available in the current context (e.g. required subsystems or connection to the controller might be unavailable). [standalone@embedded /] :shutdown { "outcome" => "failed", "failure-description" => "WFLYCTL0031: No operation named 'shutdown' exists at address []", "rolled-back" => true } {noformat} \\ *Domain* Using operation style :shutdown throws NPE. Tab completion for this operation works, which could be a little bit misleading in this case. {noformat} [domain@embedded /] shutdown --host=master The command is not available in the current context (e.g. required subsystems or connection to the controller might be unavailable).
