Я пытаюсь сериализовать некоторые объекты пользовательских классов, и я получил следующее исключение:
com.esotericsoftware.kryo.KryoException: com.sleepycat.je.EnvironmentFailureException: (JE 5.0.73) IdentityHashMap.entrySet() should not be used. See [#18167]. UNEXPECTED_STATE: Unexpected internal state, may have side effects.

У меня есть ArrayList:
ArrayList<RelationshipStorage> relationshipStorage = new ArrayList<>();
Хранилище является сериализуемым и все содержимое в нем также.
Но у меня все еще есть эта ошибка, и я не знаю, почему. В карте свойств есть только один ключ и значение. Ключ - это строка, а значение - длинная строка (хэш всего объекта).
