Я обновил продукт платформы клиента eclipse rich с версии 4.4.2 до 4.12. Все работает нормально, ожидайте помощи. Я получаю 500 ошибок. Это справка, которая использует внутренний Jetty-сервер.
Странно, что контекстная помощь и поиск помощи работают нормально. Я узнал, что помощь работает нормально, пока Eclipse rcp 4.7.3. После версии 4.7.3 она не работает для всех остальных версий.
Я не уверен, в чем проблема. Как я могу найти причину этого? Я добавил трассировку стека помощи.
