Description

When route-controller is used to start routes in a safe manner and one of the routes fails it still reports the status as UP.

camel: 
  springboot: 
    route-controller-supervise-enabled: true
    route-controller-unhealthy-on-exhausted: true
    route-controller-back-off-max-attempts: 3

No brokers defined, route will fail after the route controller gives up.

        from("kafka:hello")
                .routeId("kafka")
                .log("Hello Kafka");

While the route controller tries to restart the route, the status will be correct, DOWN.
After it gives up, it turns to an incorrect state, UP.
