Почему я получаю эту ошибку на Vaadin 14, когда я перезапускаю мое веб-приложение? Уведомление перезапустить. Не начинать с начала. Мое веб-приложение работает нормально, и я не получаю ошибок внутри кода. Так что я не могу сказать вам, где проблема, только что я получаю ошибку при запуске.
Я использую Vaadin 14 с загрузкой Spring, и это было где с самого начала проекта.
Я предполагаю, что это как-то связано с этим
