Hi,

working on issue 4505 I've noticed that class TagAttributes has the following put method:

    @Override
    public final void putAll(Map<? extends String, ?> map)
    {
        for (Object o : map.keySet())
        {
            String key = (String)o;
        }

        super.putAll(map);
    }

why this method iterates over map keys and then invoke the super version? I don't understand the purpose of this method.
