   Preondition Violations

   Type java.util.List<org.eclipse.emf.edit.provider.IItemPropertyDescriptor> of variable itemPropertyDescriptors does not match with type java.util.Map<java.lang.String,org.eclipse.emf.importer.ecore.EcoreImporterApplication.PackageInfo> of variable nameToPackageInfo
   - Make classes java.util.List and java.util.Map extend a common superclass
