   Preondition Violations

   Type java.util.List<org.eclipse.emf.edit.provider.IItemPropertyDescriptor> of variable itemPropertyDescriptors does not match with type java.util.List<org.eclipse.emf.ecore.util.FeatureMap.Entry> of variable removals
   - Make classes java.util.List and java.util.List extend a common superclass
