Class EventListenerRegistry

java.lang.Object
  com.atlassian.greenhopper.EventListenerRegistry

@Service
public class EventListenerRegistry
extends java.lang.Object

Takes care of Listeners for JIRA events. Event listeners must be handled by the plugin itself, since neither JIRA nor Plugin Framework clear out registered listeners when the plugin context goes down. If listeners stay behind they'd keep a reference to the GH classloader around from inside JIRA.
