> If a processor tries to load a ControllerService during `@OnScheduled`, then `context.getControllerService` contains a null reference to `controllerServiceProvider`. I traced this back to `StandardProcessScheduler.startProcessor`, and the reference to `controllerServiceProvider` is also `null` here. `ExecuteSQL` acquires it's connection during `@OnScheduled`.
> But once we reach `onTrigger`, everything is fine and you can retrieve a controller service without issue
