- triggerReactivation
  
  public static void triggerReactivation(Object lifecycle)
  
  Triggers a reactivation of the given lifecycle.
  The given lifecycle must be in the Lifecycle.doActivate() method or in the Lifecycle.doAfterActivate() method. Calling this method will abort the activation and cause the lifecycle to be deactivated and then activated again. If the lifecycle is not in one of the two methods, unexpected behavior will occur.
