Start by reproducing shutdown with Spring Boot 2.6.2, Spring Cloud 2021.0.0, Consul, and the gateway configuration described. Trace the shutdown-time route refresh through CachingRouteLocator, RouteDefinitionRouteLocator, and ConfigurationService while ConsulServiceRegistry deregisters the service. Done means shutdown no longer logs BeanCreationNotAllowedException.
