In public void setDependencies() for the classes that call
eventDispatcher.eventHandlerAdded() the property:

Object handlerTypeObject = ref.getProperty(Constants.EVENT_HANDLER_TYPE_PROPERTY);

should contain the value:

AbstractEvent.HandlerType handlerType

because that is no longer the case, all event handlers are not getting
the events via dispatchEvent() in EventDispatcherImpl.

Regression may have been introduced here:

Use config instead of Activator for netvirt and netvirt-providers
