class CloudAccountUpdateReq is

import com.xx.CloudAccountDiscountDTO;
import lombok.Data;

import javax.validation.Valid;
import java.io.Serializable;
import java.util.List;

@Data
public class CloudAccountUpdateReq implements Serializable {

    private Long id;

    private String note;

    private List<String> regionList;

    private List<@Valid CloudAccountDiscountDTO> discountList;

}

The field discountList is annotated with @Valid.

But, this way it works normally.

  @Valid
  private List<CloudAccountDiscountDTO> discountList;

I tested with version 1.12.18, 1.14.6 for testing and still reported the error.

I would assume that the JVM would also fail if you tried to reqd the annotations of that type. It seems like some type adds an illegal value to the annotation.

It works as expected. It's a feature of Bean Validation called Container element constraints:

• Support for validating container elements by annotating type arguments of parameterized types, e.g. List<@Positive Integer> positiveNumbers (see Container element constraints);

Can you create a stand-alone example for me, then I am happy to look into it.

I also just checked the line number. It does not seem like that you are using the latest version of Byte Buddy. Could you try updating first?

Sorry for my mistake. Version 1.14.0 is working fine
