Exception lors de la création du Bean "entityManagerFactory"
Bonjour,
J'essaie de mettre en place dans mon application l'accès aux données via Spring data avec hibernate.
Lorsque j'essaie de lancer mon application j'ai une erreur lors de la création de mon Bean :

C'est surtout la cause qui m'interpelle : Expecting Collection type.
Ma classe MatrixRow :

Je me demande si le problème vient pas du fait que mon attribut cells soit un tableau et non une liste
Si vous avez des pistes pour régler mon problème je suis preneur.
Merci
