   Preondition Violations

   Type org.eclipse.emf.ecore.impl.BasicEObjectImpl.EPropertiesHolder of variable eProperties does not match with type org.eclipse.emf.converter.util.ConverterUIUtil.DiagnosticHandler of variable diagnosticHandler
   - Make classes org.eclipse.emf.ecore.impl.BasicEObjectImpl.EPropertiesHolder and org.eclipse.emf.converter.util.ConverterUIUtil.DiagnosticHandler extend a common superclass
