    Description

      On camel 2.x and early versions of 3.x you could specify an unmarshal type that is an array

      EX

      from("direct:beginArray").unmarshal().json(JsonLibrary.Jackson, String[].class).to("mock:endArray");
       

      I've upgraded to Camel 3.7.1 and this now throws an exception
