public static void doSetMetaClass(Object self, MetaClass mc)
DefaultGroovyMethods helper method. This method was introduced as
 a breaking change in 2.0 to solve rare cases of stack overflow. See GROOVY-5285.
 The method is named doSetMetaClass in order to prevent misusages. Do not use
 this method directly unless you know what you do.self - the object for which to set the meta classmc - the metaclass
