Found it! The problem is both 'alfresco-access' and 'tagging' keys are being duplicated and you cannot such situation. Both files are core ones, inside alfresco standard libs.
So I found It had a duplicated library, alfresco-repository-20.X and alfresco-repository-21.Y added with amps and customization to the Alfresco Installation.
I removed the oldest one and the error disappeared
