   Preondition Violations

   Type org.eclipse.emf.ecore.resource.impl.ResourceImpl.ContentsEList<org.eclipse.emf.ecore.EObject> of variable contents does not match with type org.eclipse.core.resources.ResourceAttributes of variable resourceAttributes
   - Make classes org.eclipse.emf.ecore.resource.impl.ResourceImpl.ContentsEList and org.eclipse.core.resources.ResourceAttributes extend a common superclass
