Description

PropertiesUtil loads all PropertySources at startup without any parameters. Spring Boot needs to pass the Environment to the PropertySource but the PropertySource is created before Spring Boot has initialized. This change would allow the Spring Boot PropertySource to be registered manually during Spring Boot initialization.
