> A Session lacking permission to read property jcr:mixinTypes, but permission to write will overwrite existing mixins when calling Node.addMixin().
> The implementation does not check if the session has permission to read jcr:mixinTypes and assumes there are no existing values when the session does not have permission. The result is a jcr:mixinTypes property with only a single value passed to addMixin().
