Getting Route for a RouteConfiguration is null when doing manual route loading

I load the routeConfiguration like this:

loader = extendedCamelContext.getRoutesLoader();
loader.loadRoutes(resource);

On a later moment, I like to remove or update the routeConfiguration, but I first want to check if it's already loaded. To do this, I try to get the route:


 

List<Route> routes = context.getRoutes(); 
 
//or

Route route = context.getRoute(id);
