Controller tutorial doc page leads to compilation errors

[bfreuden]

Source code provided on the following pages:
https://helix.apache.org/0.9.8-docs/tutorial_controller.html
https://helix.apache.org/1.0.1-docs/tutorial_controller.html
Has compilation errors on those lines:

manager.addConfigChangeListener(controller);  // compilation error
manager.addLiveInstanceChangeListener(controller);
manager.addIdealStateChangeListener(controller);
manager.addExternalViewChangeListener(controller);  // compilation error
manager.addControllerListener(controller);

I had a look at the org.apache.helix.controller.HelixControllerMain and spotted the addListenersToController static method having this body:

manager.addControllerListener(controller);
manager.addInstanceConfigChangeListener(controller);
manager.addResourceConfigChangeListener(controller);
manager.addClusterfigChangeListener(controller);
manager.addLiveInstanceChangeListener(controller);
manager.addIdealStateChangeListener(controller);

But I have the impression it is never called in the main.

I wrote a little demo program that is only doing this:

HelixManager manager = HelixManagerFactory.getZKHelixManager(CLUSTER_NAME,
                "controller",
                InstanceType.CONTROLLER,
                ZK_ADDRESS);
manager.connect();

And it seems to be enough to operate my participants.
