stack trace:

issue reproduce repository: https://github.com/czp3009/spring-native-not-support-method-handler-with-kotlin-default-value

Possible causes:
i notice that in this issue spring finally support kotlin default value in method handler

but according to code in PR, it seems that the native hint for method handlers with method names ending in '$default' is missing
