Quand on lance la synchronisation des tables de références, on a des erreurs de style NullPointerException. Cela semble toutefois correctement bien tout importer

Exemple d'erreur : 

AmetysRuntimeScheduler_Worker-5 JCR query '//element(*, ametys:content)[(@ametys:code = 'C' and @ametys-internal:contentType = 'odf-enumeration.CodeRome4')]' executed in 3 ms
