[BUG]fastjson2不支持直接对对象进行jpath设置List中的对象

[majh1]

测试用例如下

@Getter
    @Setter
    static class User{
        private String name;
        private List<NVString> additionalInfo;
    }
    @Getter
    @Setter
    @ToString
    static class NVString{
        String name;
        String value;
    }

        public static final String JSON = "{\"name\":\"fastjson2\",\"additionalInfo\":[{\"name\":\"srv6-color\",\"value\":\"test\"},{\"name\":\"test2\",\"value\":\"3\"}]}";

    public static  String path = "$.additionalInfo[?(@.name=='srv6-color')].value";
    @Test
    public void test_fastjson2_case1(){
        User user = JsonUtil.fromJson(JSON,User.class);
        JSONPath jsonPath = JSONPath.of("$.additionalInfo[?(@.name=='srv6-color')].value");
        jsonPath.set(user, "modify");
        Assert.assertEquals(user.getAdditionalInfo().get(0).getValue(),"modify");
    }


    @Test
    public void test_fastjson_case1(){
        User user = JsonUtil.fromJson(JSON,User.class);
        com.alibaba.fastjson.JSONPath.set(user,"$.additionalInfo[?(@.name=='srv6-color')].value","modify");
        JSONPath jsonPath = JSONPath.of("$.additionalInfo[?(@.name=='srv6-color')].value");
        jsonPath.set(user, "modify");
        Assert.assertEquals(user.getAdditionalInfo().get(0).getValue(),"modify");
    }

对比fastjson和fastjson2、不支持直接对对象进行设置、会将List中的对象直接设置为null
想请教下： 是故意这么设计不支持List中对象的jpath set对象、还是bug

看源码：再JSONPathSegmentName中的

public void set(JSONPath.Context context, Object value) {
        Object object = context.parent == null
                ? context.root
                : context.parent.value;

        if (object instanceof Map) {
            Map map = (Map) object;
            Object origin = map.put(name, value);
            if (origin != null) {
                if ((context.readerFeatures & JSONReader.Feature.DuplicateKeyValueAsArray.mask) != 0) {
                    if (origin instanceof Collection) {
                        ((Collection) origin).add(value);
                        map.put(name, value);
                    } else {
                        JSONArray array = JSONArray.of(origin, value);
                        map.put(name, array);
                    }
                }
            }
            return;
        }

        if (object instanceof Collection) {
            Collection collection = (Collection) object;
            for (Object item : collection) {
                if (item == null) {
                    continue;
                }

                if (item instanceof Map) {
                    Map map = (Map) item;
                    Object origin = map.put(name, value);
                    if (origin != null) {
                        if ((context.readerFeatures & JSONReader.Feature.DuplicateKeyValueAsArray.mask) != 0) {
                            if (origin instanceof Collection) {
                                ((Collection) origin).add(value);
                                map.put(name, value);
                            } else {
                                JSONArray array = JSONArray.of(origin, value);
                                map.put(name, array);
                            }
                        }
                    }
                    continue;
                }

                ObjectReaderProvider provider = context.path.getReaderContext().getProvider();
                ObjectReader objectReader = provider.getObjectReader(item.getClass());
                FieldReader fieldReader = objectReader.getFieldReader(nameHashCode);
                if (fieldReader != null) {
                    // **此处设置为了null**
                    fieldReader.accept(item, null);
                }
            }
            return;
        }

        ObjectReaderProvider provider = context.path.getReaderContext().getProvider();
        ObjectReader objectReader = provider.getObjectReader(object.getClass());
        FieldReader fieldReader = objectReader.getFieldReader(nameHashCode);
        if (fieldReader == null) {
            return;
        }

        if (value != null) {
            Class<?> valueClass = value.getClass();
            Class fieldClass = fieldReader.fieldClass;
            if (valueClass != fieldClass) {
                java.util.function.Function typeConvert = provider.getTypeConvert(valueClass, fieldClass);
                if (typeConvert != null) {
                    value = typeConvert.apply(value);
                }
            }
        }
        fieldReader.accept(object, value);
    }
