   Preondition Violations

   Type java.util.List<org.eclipse.emf.ecore.EStructuralFeature> of variable childrenFeatures does not match with type org.eclipse.core.resources.IFile of variable workspaceFile
   - Make classes java.util.List and org.eclipse.core.resources.IFile extend a common superclass

   Preondition Violations
