Manquant de démarrage limite d'Exception lors de la lecture des messages avec une pièce jointe de fichier

Je ne sais pas pourquoi je me fais de l'exception suivante lors de la lecture d'un mail avec une pièce jointe de fichier à partir du serveur de messagerie:

Exception in thread "main" javax.mail.MessagingException: Missing start boundary

        at javax.mail.internet.MimeMultipart.parsebm<MimeMultipart.java:872)
        at javax.mail.internet.MimeMultipart.parse<MimeMultipart.java:493)
        at javax.mail.internet.MimeMultipart.getCount<MimeMultipart.java:240)
        at GetParts.handleMultipart(GetParts.java:57)
        at GetParts.main(GetParts.java:42)

Le fichier que j'utilise pour lire ces messages est:
