Я пытаюсь написать файл Excel, используя Apache Poi 5.1.0. Запрашивается веб -запрос, висит в течение нескольких минут, а затем в конечном итоге записывает файл Excel в ответ http servlet.private void writeWorkbookToResponse(XSSFWorkbook outputWorkbook, HttpServletResponse response) throws IOException {
try (OutputStream outputStream = response.getOutputStream();
BufferedOutputStream bos = new BufferedOutputStream(outputStream)) {
outputWorkbook.write(bos);
bos.flush();
}
}
< /code>
И вот соответствующая часть трассировки стека: < /p>

Каковы условия, которые Apache Poi бросает исключение по сломанной трубе? Я предполагаю, что есть некоторые общие причины этих исключений, которые я должен изучать.
