We build one main ApplicationContext and dynamically add two child contexts, each with one AnimalController. In older versions of Spring Boot (f.e. 2.2.6), both controllers could be accessed via /lizard/feed and /cat/feed, respectively. With 2.3.4, however, we only get 404 for both paths.

• ./gradlew :parent:bootRun
• curl --request GET --url http://localhost:8080/lizard/feed and curl --request GET --url http://localhost:8080/cat/feed should both result in a 200. With the latest Spring Boot version, both result in 404.
