Я понимаю, что есть много вопросов, связанных с этой темой, но все они связаны с записью ответа, а затем выполнением перенаправления / пересылки или чего-то подобного предсказуемым и легко воспроизводимым способом.
Проблема, с которой я столкнулся, заключается в том, что однажды производственное приложение неожиданно начало вызывать это исключение на случайных страницах 4-5 раз в день.Трассировка стека находится ниже.Приложение использует myfaces 1.1.9, richfaces 3.1.4.GA, tomahawk 1.1.10 и развернуто на tomcat 5.5.33.Я пытался обновить эти библиотеки, но проблема не устранена.
Видимо, когда приходит запрос, ответ уже зафиксирован.Я не знаю, почему это происходит.Чтение исходного кода Tomcat, единственный способ, которым это может быть возможно, - это если метод recycle () в Response не вызывается.Но каждый раз, когда я отлаживаю приложение, вызывается метод.То же самое происходит независимо от того, является ли запрос ajax или нет.
Я не могу воспроизвести эту ошибку, поэтому любая помощь может быть высоко оценена.
