[jira] [Created] (GROOVY-10553) Regression: Annotation on trait field is illegally duplicated

Christopher Smith created GROOVY-10553:
------------------------------------------

             Summary: Regression: Annotation on trait field is illegally duplicated
                 Key: GROOVY-10553
                 URL: https://issues.apache.org/jira/browse/GROOVY-10553
             Project: Groovy
          Issue Type: Bug
          Components: Compiler
    Affects Versions: 4.0.1
            Reporter: Christopher Smith


I have the following types:

{code}
trait ShipmentRelated {
  @NotBlank
  String shipmentId
}

class ShipmentLocationRequest extends Base implements ShipmentRelated {}
{code}

In Groovy 3, this compiles correctly:
{code}
  private java.lang.String com_example_logistics_ShipmentRelated__shipmentId;    descriptor: Ljava/lang/String;    flags: (0x0002) ACC_PRIVATE    RuntimeVisibleAnnotations:      0: #17()        javax.validation.constraints.NotBlank
{code}

In Groovy 4 with identical source, I get duplicate annotations:
{code}
  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
{code}

This causes an {{AnnotationFormatError}} at runtime.
