Передаю в TableView
1.
table.setItems(new TransactionalList<>(service.getTemplates()));
свой кастомный класс
1.
public class TransactionalList<T> extends ModifiableObservableListBase<T> {}
все работает хорошо, пока не пробую нажать на колонку для сортировки
вылетает

при этом ни на что это не влияет, т.е. в консоль вылетает, но сортировка отрабатывает и никаких видимых ошибок.
если написать вот так
1.
templatesTable.setItems(FXCollections.observableArrayList(service.getTemplates()));
ошибка не вылетает.
