question: private boolean areClassesEqual ( Class < ? > c1 , Class < ? > c2 ) { if ( isMap ( c1 ) ) { return isMap ( c2 ) ; } else if ( isList ( c1 ) ) { return isList ( c2 ) ; } else { return c1 . equals ( c2 ) ; } }
target:  When comparing literals allow subclasses of Maps and Lists to be directly compared even if they have different implementations.
