I'am migrating from alfresco 220 to alfresco 223. My application code crash because of AuthenticationUtil.getCurrentUsername() not found. And, indeed, this method doesn't exist anymore into alfresco-repository.jar\org\alfresco\repo\security\authentication\AuthenticationUtil. I suppose it is deprecated but inside the javadoc on the wiki : http://wiki.alfresco.com/wiki/Alfresco_JavaDoc Nothing is deprecated neither recommended. Which method has replaced it hence ?
