examples in LinkedHashMap and LinkedHashSet class doc use raw types

The LinkedHashMap class doc contains the following example:

     void foo(Map m) {
         Map copy = new LinkedHashMap(m);
         ...
     }

This uses raw types. It should use upgraded to use generics. Probably something like

    <K,V> void foo(Map<K,V> m) {
        Map<K,V> copy = new LinkedHashMap<>(m);
        // ...
    }
