  Overrides:
    log in class LoggerBase
  Parameters:
    `msg` - A `String` specifying the message to be written to the log file

### addLifecycleListener

    public void addLifecycleListener(LifecycleListener listener)

  Add a lifecycle event listener to this component.
  Specified by:
    addLifecycleListener in interface Lifecycle
  Parameters:
    `listener` - The listener to add

### removeLifecycleListener

    public void removeLifecycleListener(LifecycleListener listener)

  Remove a lifecycle event listener from this component.
  Specified by:
    removeLifecycleListener in interface Lifecycle
  Parameters:
    `listener` - The listener to add

### start

    public void start()
               throws LifecycleException
