Using a reference in items of array results in error

When a reference is used in items: of an array, e.g. :

type: object
description: Model for response from call to GET products requiring an array of products to be returned.
title: GetProductResponse
properties:
  Products:
    type: array
    items:
      $ref: Product.yaml

and error is thrown while resolving the references:

$ java -jar openapi-diff-cli-2.1.0-beta.4-all.jar --error --fail-on-incompatible source/specification/openapi.yaml destination/specification/openapi.yaml
Unexpected exception. Reason: Invalid ref: ./common/models/Product.yaml
java.lang.IllegalArgumentException: Invalid ref: ./common/models/Product.yaml

Files GetProductResponse.yaml and Product.yaml both reside in the same directory.

Attachment contains the source and destination folders, which contain a copy of the same openapi spec.
example.zip

Commencez par l’example.zip joint et reproduisez la commande CLI ; lisez ensuite RefPointer.java, en particulier getRefName et resolveRef, ainsi que le chemin d’appel de SchemaDiff et DeferredSchemaCache indiqué dans la trace. C’est terminé lorsque le $ref vers le fichier frère de l’élément du tableau est résolu sans l’exception Invalid ref et que la comparaison se termine.
