Without Kapt Configured the @ConfigurationProperties are not available in container labels org.springframework.boot.spring-configuration-metadata.json and org.springframework.cloud.dataflow.spring-configuration-metadata.json
When Kapt is configured then the properties are available.
The configuration properties are always working as expected in terms of populating values.
