FlexUnit / Bug

Поймал редкий баг. После копирования большого проекта из одного Eclipse проекта в другой, отпали все flexunit тесты, и начал получать неприятное ошибки в каждом:

Ошибка

Решение

Проблема оказалась в конфликте библиотек flexUnit, среди исходников затесались их разные версии (flex и as3)
Единственное упоминание аналогичной проблемы: http://forums.adobe.com/thread/659296. Починил удалением лишних swc-шек.
