   Preondition Violations

   Type java.util.List<org.eclipse.emf.edit.provider.IItemPropertyDescriptor> of variable propertyDescriptors does not match with type org.eclipse.core.resources.ResourceAttributes of variable resourceAttributes
   - Make classes java.util.List and org.eclipse.core.resources.ResourceAttributes extend a common superclass
