Seems like you indeed have a cyclic dependency… The process-engine configuration is needed by your listeners (historyService), which in turn depends on the listeners. You can either use the ProcessEngines.getDefault() in your listeners instead of injecting the historyService. OR make the listener an InitilizingBean (or applicationContextAware not sure about the name) and extract the historyService from the app-context. OR find out another way to prevent the cyclic dependency
