I'm guessing that you might need to use GenericEntity to capture the
generic type of the collection. If the method returns say
List<Something> directly then the runtime can determine the generic
type (Something) but if it returns Response then the generic type is
lost due to type erasure.
See example 1 in the javadoc:
