我试图使用jackson库序列化java动态代理，但出现以下错误：

public interface IPlanet {
String getName();
}
Planet implements IPlanet {
    private String name;
    public String getName(){return name;}
    public String setName(String iName){name = iName;}
}
IPlanet ip = ObjectsUtil.getProxy(IPlanet.class, p);
ObjectMapper mapper = new ObjectMapper();
mapper.writeValueAsString(ip);
//The proxy generation utility is implemented in this way:
/**
 * Create new proxy object that give the access only to the method of the specified
 * interface.
 * 
 * @param type
 * @param obj
 * @return
 */
public static <T> T getProxy(Class<T> type, Object obj) {
    class ProxyUtil implements InvocationHandler {
        Object obj;
        public ProxyUtil(Object o) {
            obj = o;
        }
        @Override
        public Object invoke(Object proxy, Method m, Object[] args) throws Throwable {
            Object result = null;
            result = m.invoke(obj, args);
            return result;
        }
    }
    // TODO: The suppress warning is needed cause JDK class java.lang.reflect.Proxy
    // needs generics
    @SuppressWarnings("unchecked")
    T proxy = (T) Proxy.newProxyInstance(type.getClassLoader(), new Class[] { type },
            new ProxyUtil(obj));
    return proxy;
}

我有个例外：

Exception in thread "main" com.fasterxml.jackson.databind.JsonMappingException: No serializer found for class $Proxy11 and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationConfig.SerializationFeature.FAIL_ON_EMPTY_BEANS) )

问题似乎与hibernate代理对象序列化时发生的问题相同，但我不知道如何以及是否可以使用jacksonhibernate模块来解决问题。
更新：jackson2.0.6版本解决了这个bug
