native-image compile failed ( java.lang.StackOverflowError) when field type is enum.

[imgoby]

<dubbo.version>3.3.0-beta.1</dubbo.version>

public enum MyType {
    OK,
    FAILED
}

public class DemoServiceImpl implements DemoService {

    @Override
    public String sayHello(MyType type) {
        return "Hello " + type.name();
    }
}

public interface DemoService {
    String sayHello(MyType type);
}

if field type is enum ，it causes this exception:

This judgment seems to be acceptable

[CrazyHZM]

@imgoby
This does not seem to be supported by spring itself.

[imgoby]

this code file is under dubbo project.
org.apache.dubbo.config.spring6.utils.AotUtils

it is dubbo's code bug. not spring.

@imgoby
You are right. It will be fixed in the next version.
