2.6.0 update overrides the default behavior for the PropertyPlaceholderHelper

The 2.6.0 update seems to automatically configure a default for the whole application. This code works perfectly fine with 2.5.0 but crashes in 2.6.0 if spring.horse is undefined.

This is caused by a change in SwaggerCommonConfiguration when PropertySourcesPlaceholderConfigurer was replaced with PropertyPlaceholderConfigurer

I think that the new behavior is actually the default that spring boot had, I just wanted to log a side effect that I received by updating the library.

@SpringBootApplication
@RestController
@EnableSwagger2
public class Swagger2SpringBoot {

    @Value("${spring.horse}")
    private String horse;

    public static void main(String[] args) throws Exception {
        new SpringApplication(Swagger2SpringBoot.class).run(args);
    }

    @RequestMapping(value = "/dummy")
    String meGet() {
        return null;
    }


}
