   Preondition Violations

   Type java.util.List<org.eclipse.emf.ecore.EDataType> of variable memberTypes does not match with type org.eclipse.emf.converter.util.ConverterUIUtil.DiagnosticHandler of variable diagnosticHandler
   - Make classes java.util.List and org.eclipse.emf.converter.util.ConverterUIUtil.DiagnosticHandler extend a common superclass
