Just construct a new ArrayList wrapping the keyset of the request parameter map. I only wonder how it’s useful to have it as List<String>. A Set<String> would make much more sense as parameter names are supposed to be unique (a List can contain duplicate elements). A Set<String> is also exactly what the map’s keyset already represents.

Of course the “You shall not instantiate an item of this class” statement has been violated, but if this is the logic behind that, then we should all throw AssertionErrors everywhere, and that is obviously not what happens.
