   Preondition Violations

   Type java.util.Collection<> of variable affectedObjects does not match with type org.eclipse.core.resources.ResourceAttributes of variable resourceAttributes
   - Make classes java.util.Collection<> and org.eclipse.core.resources.ResourceAttributes extend a common superclass
