[collections] fails the method TransformedMap.transformedMap

Sorry, my english  is very bad.

PROBLEM: I think Method MapUtils.transformedMap fails because method 
TransformedMap.transformedMap fails too, because internally the constructor 
TransformerMap takes the parameters but it doesn´t perform anything with them.

See Attachment Test Case:

I want to add 5 to each one of the members of  the Map:

1) FIRST TEST: DOESN´T WORKS (because internally the constructor TransformerMap 
takes the parameters but it doesn´t perform anything with them.)


2) SECOND TEST: IT WORKS, but i think that it is not a correct solution or i 
don´t understand the MapUtils.transformedMap philosophia.


3) One possible solution could be changing TrasformerMap constructor like this:

    protected TransformedMap(Map map, Transformer keyTransformer, Transformer 
valueTransformer) {
        super(map);
        this.keyTransformer = keyTransformer;
        this.valueTransformer = valueTransformer;
         
        //New
        transformMap(map);
}

4) Another possible solution could be changing the method 
TransformedMap.transformMap from protected to public.
