Annotation with type, type lost to a string #222

Take this class that is using jackson databinding :

package com.example.android.apis.annotations;

import com.fasterxml.jackson.annotation.JsonSubTypes;
import com.fasterxml.jackson.annotation.JsonTypeInfo;

@JsonSubTypes(
    {
      @com.fasterxml.jackson.annotation.JsonSubTypes.Type(name="subObject", value=MrSubObject.class)
    }
  )
@JsonTypeInfo(defaultImpl=MrObject.class, include=JsonTypeInfo.As.PROPERTY, 
property="type", use=JsonTypeInfo.Id.NAME, visible=true)
public class MrObject
{

}

Compile it and dex it (like any android build), running dex2jar will produce a 
class where type information has been replaced by string :

package com.example.android.apis.annotations;

import com.fasterxml.jackson.annotation.JsonSubTypes;
import com.fasterxml.jackson.annotation.JsonTypeInfo;
import com.fasterxml.jackson.annotation.JsonTypeInfo.As;
import com.fasterxml.jackson.annotation.JsonTypeInfo.Id;

@JsonSubTypes({@com.fasterxml.jackson.annotation.JsonSubTypes.Type(name="subObje
ct", value="Lcom/example/android/apis/annotations/MrSubObject;")})
@JsonTypeInfo(defaultImpl="Lcom/example/android/apis/annotations/MrObject;", 
include=JsonTypeInfo.As.PROPERTY, property="type", use=JsonTypeInfo.Id.NAME, 
visible=true)
public class MrObject
{
}

At android runtime you will get :
