https://openliberty.io/docs/latest/reference/feature/springBoot-3.0.html indicates that the feature supports 3.x.x. Then, in https://openliberty.io/docs/latest/deploy-spring-boot.html, it's unclear that this feature actually supports Spring Boot versions beyond 3.0.x.
If your application uses Spring Boot 3.0.4+, enable the springBoot-3.0 feature.
Update the deploy-spring-boot document to indicate Spring Boot 3.5.x is supported. Or, 3.x.x is supported via the springBoot-3.0 feature.
