Le problème principal reste que TinkerPop ne supporte pas l'absence d'attribut "id" sur les "edge", alors que la spéc GraphML précise bien que cet attribut est optionnel. Heureusement, grâce à Java 8, plus ça va plus le code de TinkerPop est illisible, bientôt on ne pourra même plus arriver à lire ce genre de détail dans le code.

A priori corrigé [https://github.com/gephi/gephi/issues/1585]
