> The framework initialization process includes asynchronous enabling of
> Controller Services using a Runnable command submitted to the shared
> Timer-Driven {{ScheduledExecutorService}}. The
> {{StandardControllerServiceNode}} {{enable}} method initiates the command,
> which first checks the Validation Status of the Controller Service before
> calling {{OnEnabled}} methods.
> In deployments with multiple Controller Services, the enabling process can
> take several minutes while waiting on asynchronous validation to be
> completed. The Runnable enable command reschedules itself when the Controller
> Service is not valid, waiting for asynchronous validation to be completed. As
> a result of waiting for validation, the enable command retries multiple times
> and does not complete until after Controller Service validation.
