Spring Cloud Config spring-cloud-config-server 3.0.0-M4 error with Spring Boot 2.4.0

Is Cloud 3.0.0-M4 expected to work with Spring Boot 2.4.0? I do have Eureka 3.0.0-M4 (client and server) working with 2.4.0.

Getting an error on startup. This is coming from the spring-cloud-config-server dependency. When I comment that out, I can start up. java.lang.VerifyError: Cannot inherit from final class. I've done a maven project update, clean, mvn clean install, etc. Seems to be some conflict somewhere.
