ObjectInputStream.readObject() java.io.InvalidClassException: java.util.HashMap; локальный класс несовместим: поток classdesc с graalVM

• Укажите подробную информацию о своей цели:

Используйте return (Map<?, ?>) objectInputStream.readObject();, чтобы получить карту без сбоев в собственном образе graalVM.

• Покажите код:

Код на самом деле очень простой. Всего два файла, которые можно скопировать и вставить в вашу среду для воспроизведения.

private static Map<?, ?> getNormalizedMap(String encoded) {
        try (var objectInputStream = new ObjectInputStream(new ByteArrayInputStream(Base64.getDecoder().decode(encoded)))) {
            return (Map<?, ?>) objectInputStream.readObject(); // issue here !
        } catch (IOException | ClassNotFoundException | IllegalArgumentException e) {
            LOGGER.error("encoded = {}", encoded, e);
            return Map.of();

• Опишите ожидаемые результаты:

return (Map<?, ?>) objectInputStream.readObject(); вернет правильную карту. В случае этой проблемы ожидаемый результат должен быть

1. просто запустите mvn clean install и запустите jar
2. сделайте http-запрос, curl http://localhost:8080/graalissue
3. ожидаемый результат: «Здесь должно быть 41 => 41»

Я ожидал увидеть «Здесь должно быть 41 => 41» как для собственного, так и для неродного изображения.

• Опишите фактические результаты:

1. запустите mvn -Pnative spring-boot:build-image, это создаст собственный образ graalvm
2. run docker tag docker.io/library/graalissue:0.0.1-SNAPSHOT graalissue:latest
3. docker run -p 8080:8080 graalissue:latest
4. curl http://localhost:8080/graalissue Выходной размер будет 0.

• Включите все сообщения об ошибках:

Это не удается ни с одним, ни с другим

1. прошу добавить java.util.Collections$UnmodifiableMap к serialization-config.json
2. если я добавлю java.util.Collections$UnmodifiableMap к serialization-config.json (в правильности чего я даже не уверен), я получу java.io.InvalidClassException: java.util.HashMap; local class incompatible: stream classdesc

Если я ничего не добавляю в serialization-config.json, произойдет ошибка, и трассировка стека попросит меня добавить java.util.Collections$UnmodifiableMap в serialization-config.json.

Если я добавлю его, я получу следующую трассировку стека:

java.io.InvalidClassException: java.util.HashMap; local class incompatible: stream classdesc serialVersionUID = 362498820763181265, local class serialVersionUID = -3563561681480877083

• Вопрос:

Как обойти эту проблему?

Как правильно return (Map<?, ?>) objectInputStream.readObject(); использовать собственный образ graalVM, поскольку код в неродном образе вообще не имеет проблем?
