Description

I have the following types:

trait ShipmentRelated {
  @NotBlank
  String shipmentId
}

class ShipmentLocationRequest extends Base implements ShipmentRelated {}

In Groovy 3, this compiles correctly:

  private java.lang.String com_example_logistics_ShipmentRelated__shipmentId;
    descriptor: Ljava/lang/String;
    flags: (0x0002) ACC_PRIVATE
    RuntimeVisibleAnnotations:
      0: #17()        javax.validation.constraints.NotBlank

In Groovy 4 with identical source, I get duplicate annotations (annotation sections?):

  private java.lang.String com_example_logistics_ShipmentRelated__shipmentId;
    descriptor: Ljava/lang/String;
    flags: (0x0002) ACC_PRIVATE
    RuntimeVisibleAnnotations:
      0: #17()        javax.validation.constraints.NotBlank
    RuntimeVisibleTypeAnnotations:
      0: #17(): FIELD        javax.validation.constraints.NotBlank

This causes an AnnotationFormatError at runtime.
