Refresh server.port of a Spring Cloud Config Client dynamically via /actuator/refresh

Question

Is it possible to make a Spring Cloud Config Client application refresh its configuration dynamically in a way, that it would restart its web server on a different "server.port" that has been read from updated configuration via Spring Cloud Config Server?

With the simplest example project (just one RestController using spring-boot-starter-web) with the "application.properties" below, "/actuator/refresh" works fine for "normal" properties.

Having "server.port: 12345" in the config (config-client-default.yml) provided by the config server, the config client properly starts on port 12345. When I change the configuration file served by the config server (e.g. to "server.port: 8080") and call the "/actuator/refresh" endpoint of the client (e.g. via "curl -sX POST http://localhost:12345/actuator/refresh", I can see that the configuration had been re-read from the config server, but the client does not restart its web server on the new port (8080).

Is it possible to dynamically refresh (reload) "server.port" using "/actuator/refresh", preferably with as little additional code as possible? Thanks in advance.

### Changed the client configuration served by the config server :
$ curl -sS http://localhost:8888/config-client/default | json_pp | fgrep 'server.port'
            "server.port" : 8080

### Calling the refresh endpoint :

$ curl -sX POST http://localhost:12345/actuator/refresh
["config.client.version","server.port"]

### (Config client still running on port 12345 - not 8080)
$ curl -sX POST http://localhost:12345/actuator/refresh
