Springdoc works with war but cannot start when embedded within an ear (Wildfly31 + JDK17)

I was using spring-core 6.1.5, springdoc-openapi-starter-webmvc-ui 2.5.0. When i packaged my application as war and deploy to Wildfly31 running on JDK17, it was working fine and I am able to access both api-docs and swagger-ui.html. However, when i packaged as ear, it was not able to startup. Both packages have the exact same classpath, except that war has the dependencies in the /lib folder while ear has the dependencies in the ear with the same jars in the war's manifest. The error is quite unexpected:

Caused by: java.lang.NoClassDefFoundError: Failed to link org/springframework/web/servlet/support/AbstractDispatcherServletInitializer (Module "deployment.springdocweb-module-7.0.0-SNAPSHOT.ear.spring-webmvc-6.1.5.jar" from Service Module Loader): org/springframework/web/context/AbstractContextLoaderInitializer

I am trying to upgrade my REST module previously using Springfox to Springdoc so that I can run my applicaton on JDK17 with Jakarta API. I was able to get my sample app to run on Springboot and War but just not in ear.

I fixed this issue by placing all the dependencies in the /lib folder of the ear file, instead of the root. It seems that after adding the springdoc-openapi-starter-webmvc-ui.jar, the autoconfigure is looking for the jars in the /lib.
