> Hi guys,
>  
> I've got a simple app using Avro Reflection:
>  
> {code:java}
> public class App {
>   public static void main(String[] args) {
>     testReflection();
>   }
>   static class User {
>     public String first = "Andy";
>     public String last = "Le";
>   }
>   static void testReflection(){
>     // get the reflected schema for packets
>     Schema schema = ReflectData.AllowNull.get().getSchema(User.class);
>     System.out.println(schema.toString(true));
>   }
> {code}
> The output on console will be:
> {noformat}
> {
>   "type" : "record",
>   "name" : "User",
>   "namespace" : "App",
>   "fields" : [ {
>     "name" : "first",
>     "type" : [ "null", "string" ],
>     "default" : null
>   }, {
>     "name" : "last",
>     "type" : [ "null", "string" ],
>     "default" : null
>   } ]
> }
> {noformat}
>  
> As you can see, there's no default values for fields. Would you please tell me how to obtain such values?
> Thank you.
