Проблема с ProGuard и RoboGuice с аннотациями @Inject

У меня проблемы с proguard при оптимизации моего приложения для Android. Похоже, что что-то сделано с классом аннотации (@ com.google.inject.Inject), что Dalvik / Harmony не устраивает во время выполнения.

java.lang.annotation.IncompleteAnnotationException: Необязательный элемент не завершен для аннотации com.google.inject.Inject

com.google.inject.Inject выглядит так (часть Guice):

@Target(value={ElementType.METHOD, ElementType.CONSTRUCTOR, ElementType.FIELD})
@Retention(value=java.lang.annotation.RetentionPolicy.RUNTIME)
@Documented
public abstract @interface com.google.inject.Inject extends Annotation {
  public abstract boolean optional() default false;
}

Вот ошибка при запуске:
