Spring Cloud's #RefreshScope causes controller mapping collision with itself - spring

Question

I'm trying to follow the tutorial at this link to test out Spring Cloud, but whenever I wire up my controller with #RefreshScope I get an error that the RequestMapping has already been taken. If I drop #RefreshScope things work great and I see the value from the config-server.
Any help would be appreciated. Thanks!
Code:
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#SpringBootApplication
public class WebCloudPoc {
public static void main(String[] args){
SpringApplication.run(WebCloudPoc.class, args);
}
#RestController
#RefreshScope
public static class ProjectNameRestController {
#Value("${configuration.projectName}")
private String projectName;
#RequestMapping("/project-name")
public String projectName() {
return this.projectName;
}
}
}
The log output is below:
