James Carman commented on COLLECTIONS-194:
------------------------------------------
I would probably pass in TransformerUtils.nopTransformer() rather than null
when you don't want to transform the map values. That would be more elegant.
Of course, a method call that merely returns the parameter would probably take
longer in practice than the null checks.
