Hi,How did you get this jar ?? I dont see this package present in the adobe repository under https://repo.adobe.com/nexus/content/groups/public/com/adobe/cq/

Restart is not required. Which AEM version are you trying. I will try once and let you know if its a problem with my instance aswell.Meanwhile, try on a new workflow model and see if you are still facing the issue.
