Shouldn't these have the nested annotation on them?

**Comment From: wilkinsona** From [the documentation](https://docs.spring.io/spring-boot/specification/configuration-metadata/annotation-processor.html#appendix.configuration-metadata.annotation-processor.automatic-metadata-generation.nested-properties): > The annotation processor automatically considers inner classes as nested properties … You can use the `@NestedConfigurationProperty` annotation on a field to indicate that a regular (non-inner) class should be treated as if it were nested. All of the fields above are of types that are inner-classes so `@NestedConfigurationProperty` isn't needed. Those properties, which are all nested beneath `Registration`, don't appear in the [documentation appendix](https://docs.spring.io/spring-boot/appendix/application-properties/index.html#appendix.application-properties.security) (or the metadata from which the documentation is derived) due to https://github.com/spring-projects/spring-boot/issues/9945.
