Мы время от времени получаем ошибки в нашем приложении GWT / GAE, связанные с Guice. Трассировка стека ниже.
В большинстве случаев это длится всего пару минут и всего несколько запросов. Самое позднее было это утро, когда это происходило почти в течение часа для более чем 20 запросов.
Кажется, что каждая ошибка в одном и том же месте: HttpSessionSecurityCookieFilter.getSession.
