Actually I've been wondering whether HeaderProvider has any real
utility. @HeaderParam will work with any type that has a String
constructor, a List<String> constructor or a static valueOf(String)
method. Headers returned via a Response can be serialized by using the
values toString method. HeaderProvider allows you to decouple the
value class and the serialization/deserialization logic but its not
clear to me if that is particularly useful so far.
