Invocation of an annotation field references an executable.

[GerardPaligot]

Assuming you have this annotation:

@interface Parameter {
  String value();
}

If you invocate the field value, Spoon build a CtExecutableReference and you can't get the field declaration cause of this reference.

CtAnnotationType contains implicit methods for each field
OR
CtAnnotationTypeField implements CtField,CtMethod
