How to detect delivery of change sets into a stream using Java API?

Right now I am trying to programmatically detect when other users deliver Change Sets to a stream using the plain Java API, but I am not currently having any luck detecting detecting any events or deliveries. I'm rather new to this and don't know if I missed something simple, or need to try a completely different approach altogether. Any help is appreciated.

Code:

public void addListener(IWorkspaceConnection monitoredStream) {
    ArrayList<Object> eventList = this.buildEventList();
    for (Object o : eventList) {
       monitoredStream.addGenericListener(o, new MyIListener());
    }
}
public ArrayList<Object> buildEventList() {
    ArrayList<Object> events = new ArrayList<>();
    events.add(IChangeHistoryEvent.ACCEPT_CHANGESETS);
    events.add(IChangeHistoryEvent.ACCEPT_COMBINED);
    events.add(IChangeHistoryEvent.CLOSE_CHANGE_SETS);
    events.add(IChangeHistoryEvent.CONFLICTS_UPDATED);
    events.add(IChangeHistoryEvent.CREATE_CHANGE_SET);
    events.add(IChangeHistoryEvent.DELIVER);
    events.add(IChangeHistoryEvent.DISCARD_CHANGE_SETS);
    events.add(IChangeHistoryEvent.HISTORY_RESTRUCTURED);  
    events.add(ICommitEvent.COMMIT);
    events.add(IConfigurationUpdateEvent.CONFIGURATION_UPDATED);
    events.add(ICurrentChangeSetEvent.SET_CURRENT_CHANGESET);
    events.add(IPropertyChangeEvent.ADD);
    events.add(IPropertyChangeEvent.ADD_MANY);
    events.add(IPropertyChangeEvent.MOVE);
    events.add(IPropertyChangeEvent.NO_INDEX);
    events.add(IPropertyChangeEvent.REMOVE);
    events.add(IPropertyChangeEvent.REMOVE_MANY);
    events.add(IPropertyChangeEvent.SET);
    events.add(IPropertyChangeEvent.UNSET);
    events.add(IQueryEvent.QUERY_ADDED_EVENT_TYPE);
    events.add(IQueryEvent.QUERY_CHANGED_EVENT_TYPE);
    events.add(IQueryEvent.QUERY_CREATED_EVENT_TYPE);
    events.add(IQueryEvent.QUERY_DELETED_EVENT_TYPE);
    events.add(IQueryEvent.QUERY_EXECUTION_DONE_EVENT_TYPE);
    events.add(IQueryEvent.QUERY_EXECUTION_START_EVENT_TYPE);
    events.add(ISharedItemChangeEvent.SHARED_ITEM_CHANGE_EVENT_TYPE);
    return events;
}
