Requality

1. Создала проект с двумя требованиями, у каждого требования есть свой фрагмент.
2. У одного фрагмента испортила json, у другого удалила json.
3. Переоткрыла Eclipse. В окне Problems появились ошибки, как и ожидалось. При попытке открыть ошибки возникают окна с ошибкой, этого быть не должно.

Проект приложен к тикету.

Содержимое ошибки:
