    Assert.assertEquals(1, a1.getEvents(Action.Hook.POST).size());
    Event e2 = mock(Event.class);
    a1.addEvent(Action.Hook.POST, e2);
    Assert.assertEquals(2, a1.getEvents(Action.Hook.POST).size());
    String str = a1.toString();
    // Check for issue #203. Only one occurrence of the event is reported.
    Assert.assertEquals(str.indexOf(String.valueOf(e2.hashCode())), str.lastIndexOf(String.valueOf(e2.hashCode())));
