Throws: IllegalStateException if this component has already been started LifecycleException if this component detects a fatal error that prevents this component from being used

Gracefully terminate the active cluster component.
This will disconnect the cluster communication channel, stop the listener and deregister the valves from host or engine.

Note:
The sub elements receiver, sender, membership, listener or valves are not removed. You can easily start the cluster again.

Throws: IllegalStateException if this component has not been started LifecycleException if this component detects a fatal error that needs to be reported
