выглядит как ошибка в моем коде, но я не могу ее найти.

У вас есть идеи, где ошибка?

Я использую Tomcat 8.0.23 с Mojarra 2.2.6. В firebug я не вижу ошибок.

Моя ошибка. Здесь полный вывод http://pastebin.com/P86Xqder –

Пожалуйста, проверьте этот файл https://www.dropbox.com/s/yru3k3ycrz1541j/Download_test.zip?dl=0 Не забудьте поставить некоторые файлы под/opt каталог или изменить расположение каталога. –

Вы должны получить OutputStream от ответа и связать его только один раз, не более и более внутри цикла while.

Попробуйте сделать что-то вроде этого

OutputStream outStream = response.getOutputStream(); 

    byte[] buffer = new byte[1000]; 
    int bytesRead = -1; 

    while ((bytesRead = bIn.read(buffer)) != -1) { 
     outStream.write(buffer, 0, bytesRead); 
    } 

    facesContext.getResponseComplete(); 

    bIn.close(); 
    outStream.close();

Я проверил ваше предложенное исправление, но все же вижу ту же ошибку. –

Глупый вопрос, вы перестроили свое приложение? :) try mayby также, если изменение BufferedInputStream на FileInputStream поможет вам – Czarny

Да, я его перестрою. –
