StackOverflowError при использовании сохранения/вставки MongoRepository

Я пытаюсь использовать репозиторий mongo для сохранения/вставки класса Key-Value оболочки в мою mongoDB.

модель, которую я пытаюсь сохранить:

@Data
@AllArgsConstructor
@Document(collection = "futureTask")
public class FutureTask {

    @Id
    private Configuration configuration;
    private ScheduledFuture<?> future;
}

Репозиторий был реализован следующим образом:

public interface FutureTaskRepository extends MongoRepository<FutureTask, Configuration> {
    FutureTask findByConfiguration(Configuration configuration);

    boolean existsByConfiguration(Configuration configuration);
}

вызов FutureTaskRepository производится следующим образом:

ScheduledFuture<?> future = this.schedule(new RunnableTask(configuration), new CronTrigger(configuration.getCron()));
FutureTask futureTask = new FutureTask(configuration, future);

futureTaskRepository.insert(futureTask);

Я получаю следующую ошибку:

У monoDB, похоже, есть проблемы с такими постоянными объектами. сделал обходной путь, создав собственный репозиторий с хранилищем synchronizedCollection. сейчас не использую mongoDB или любую другую БД.

@Repository
public class FutureTaskRepository {

    // collection of futureTasks
    private Collection<FutureTask> futureTasks = Collections.synchronizedCollection(new ArrayList<FutureTask>());

    public Collection<FutureTask> findAll() {
        return this.futureTasks;
    }

    public FutureTask find(FutureTask futureTask) {
        Optional<FutureTask> optional = this.futureTasks.stream().filter(task -> task.equals(futureTask)).findFirst();
        return optional.orElse(null);
    }

    public FutureTask findByConfiguration(Configuration configuration) {
        Optional<FutureTask> optional = this.futureTasks.stream().filter(task -> task.getConfiguration()
                .equals(configuration)).findFirst();

        return optional.orElse(null);
    }

    public void insert(FutureTask futureTask) {
        this.futureTasks.add(futureTask);
    }

    public void deleteAll() {
        this.futureTasks.clear();
    }

    public void delete(FutureTask futureTask) {
        FutureTask task = this.find(futureTask);
        this.futureTasks.remove(task);
    }

    public boolean exists(FutureTask futureTask) {
        return this.futureTasks.contains(futureTask);
    }

    public boolean existsByConfiguration(Configuration configuration) {
        FutureTask futureTask = this.findByConfiguration(configuration);
        return this.exists(futureTask);
    }
}
