serializeUsing在接口类型的字段上的问题

[wensiqun]

下面getMyObject方法获取的是同样内容个对象，区别是一个用HashMap一个用TreeMap。但第二次序列化的时候将不会用serializeUsing中指定的类去序列化

public class Mock {

	@Test
	public void test() {
		Assert.assertEquals(
		    JSON.toJSONString(getMyObject(new HashMap<String, Name>())),
		    JSON.toJSONString(getMyObject(new TreeMap<String, Name>()))
		);
	}

	private static MyObject getMyObject(Map<String, Name> names) {
		MyObject mapObj = new MyObject();
		mapObj.setNames(names);
		Name name = new Name();
		name.setFirst("foo");
		name.setSecond("boo");
		names.put("mock", name);
		return mapObj;
	}

	public static class NameMapCodec implements ObjectSerializer {

		@Override
		public void write(JSONSerializer serializer, Object object, Object fieldName, Type fieldType, int features) throws IOException {
			JSONObject names = new JSONObject();
			for(Map.Entry<String, Name> entry :
					((Map<String, Name>)object).entrySet()) {
				Name name = entry.getValue();
				names.put(entry.getKey(), name.getFirst() + ":" + name.getSecond());
			}
			MapSerializer.instance.write(serializer, names, fieldName, JSONObject.class, features);
		}

	}

	public static class MyObject {

		@JSONField(serializeUsing = NameMapCodec.class)
		private Map<String, Name> names;

		public Map<String, Name> getNames() {
			return names;
		}

		public void setNames(Map<String, Name> names) {
			this.names = names;
		}

	}

	private static class Name {

		private String first;

		private String second;

		public String getFirst() {
			return first;
		}

		public void setFirst(String first) {
			this.first = first;
		}

		public String getSecond() {
			return second;
		}

		public void setSecond(String second) {
			this.second = second;
		}
	}

}

貌似问题处在FieldSerializer中

    Class<?> valueClass = propertyValue.getClass();
    ObjectSerializer valueSerializer;
    if (valueClass == runtimeInfo.runtimeFieldClass) {
        valueSerializer = runtimeInfo.fieldSerializer;
    } else {
        valueSerializer = serializer.getObjectWriter(valueClass);
    }

runtimeInfo会缓存第一次序列化时候的类型即HashMap，第二次TreeMap将进入else中。
