[jboss-jira] [JBoss JIRA] (WFLY-5351) querying TimerService information from CLI fails for canceled timer

querying TimerService information from CLI fails for canceled timer ------------------------------------------------------------------- Key: WFLY-5351 URL: https://issues.jboss.org/browse/WFLY-5351 Project: WildFly Issue Type: Bug Components: EJB Affects Versions: 8.2.1.Final, 10.0.0.CR2, 10.0.0.CR4, 10.0.0.CR5 Environment: probably not relevant but here is my environment {{Java Version : 1.8.0_60 Java Vendor : Oracle Corporation OS Hostname : PAMWX125 OS Architecture : amd64 OS Name : Windows 7 }} Reporter: Matthieu Brouillard Assignee: Matthieu Brouillard Fix For: 12.0.0.Alpha1 Attachments: WFLY-5351diff, patch1.diff, timer-cli-failure.zip When (at least) a persistent calendar timer is created then cancelled, querying TimerService information via CLI (script or library) fails when retrieving also runtime information. We discovered the issue because our arquillian tests are failing due to some code in arquillian that fires the equivalent of the provided CLI command below when remotes tests are executed. Attached is a proposed patch and a demo project to reproduce in a simple way.
