As mentioned in spring-cloud/spring-cloud-config#1856, override-none property is not working without bootstrap configuration.
It was useful feature but can't be used without bootstrap configuration.
It will be better to describe the information in the spring cloud documentation.

This is already called out here https://docs.spring.io/spring-cloud-config/docs/4.0.4/reference/html/#_using_bootstrap_to_override_properties

Oh, I overlooked that, great!

spring-cloud/spring-cloud-config@599c060

That's been added since v3.1.7. (I read Spring Cloud Config documentation of version 3.0.x)

It will be better if the explanation is added to the comment of the override-none property.
