java.lang.ExceptionInInitializerError Exception lors de la création de Contexte de l'Application au Printemps

Je pratique avec le Printemps, et je suis de mieux en java.lang.ExceptionInInitializerError exception lorsque j'essaie d'instancier le contexte. L'Exception apparaît ci-dessous, avec mon code qui suit. J'ai simplifié mon expérience d'avant.
