SpringBoot Version: 3.0.0
SnakeYAML Version: 1.33

When using YAML achors in an application.yml configuration file to re-use configuration blocks, for example:

some:
  path: &anchor
    config: 
      key: value
  anotherpath: 
     << : *anchor

Spring Boot throws an UnsupportedOperationException within Snakeyaml's SafeConstructor class during start up due to a modification on a mutable collection (see below).

However, same configuration works fine with Spring Boot 2.7.5. (same snakeyaml version).

Thanks a lot in advance for any ideas.

@qugemingzi you will need to upgrade to a supported version as 3.0.x is not OSS supported anymore. See https://spring.io/projects/spring-boot#support
