Я недавно начал помогать коллеге в отладке проблемы сбоя видео в ее приложении Java Swing. Приложение выполняет собственный вызов fobs4jmf.dll для воспроизведения файлов .avi. Иногда, не всегда, нативный код приводит к сбою приложения. Я не писал оригинальное заявление, а инженера, который сделал, давно уже нет; кто-нибудь может дать некоторое представление? Файл ошибок выглядит следующим образом:

Ошибка, по-видимому, впервые возникла, когда ее системы были переведены на Windows 7 из Windows XP (вы можете начать молча ругаться и пожимать руку ИТ-отделам повсюду); но возвращение машин к Windows XP не решило проблему.
Стоит также повторить, что эта ошибка не всегда возникает! Иногда приложение работает нормально, а иногда происходит сбой при запуске собственного кода JMF.
Спасибо за любую помощь!
