дружки. Я использую библиотеку vividolutions JTS (1.13) для Точек и Полигонов в своем приложении, но когда я пытаюсь преобразовать геометрические объекты в JSON, мое приложение не работает. Вот мой источник:

@RequestMapping(value = "/test_point", method = RequestMethod.GET, produces = "application/json;charset=UTF-8")
@ResponseBody
public Map<String, Object> testPoint() {

    Point point = geometryFactory.createPoint(new Coordinate(37.73, 60.45));

    return RequestMapBuilder.getInstance()
            .addAttribute("point", point)
            .build();
}

И есть JSON, который я получил от клиента:

{"point":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope":{"envelope": AND SO ON...

Также мое приложение выдает это исключение:
