在 Eclipse UML2 3.1 中，如果构造型 B 是构造型 A 的泛化，那么 B 是否继承 A 的元类扩展？

Question

直到最近，我还在使用旧版本的 Eclipse UML2 (2.4)，这可以正常工作。更新到 Eclipse UML2 3.1 后，当我尝试将从另一个构造型泛化的构造型应用于适当的扩展元类的元素时，我收到 IllegalArgumentException。单步查看 eclipse uml 源表明构造型的基础 Ecore 模型中缺少属性“base_Class”。

Java测试代码：

// Init a resource set to load the standard UML profiles
ResourceSet rset = null;
{
  rset = new ResourceSetImpl();

  rset.getPackageRegistry().put("http://www.eclipse.org/uml2/3.0.0/UML", UMLPackage.eINSTANCE);      

  // Register the UML resource factory
  rset.getResourceFactoryRegistry().getExtensionToFactoryMap().put(UMLResource.FILE_EXTENSION, UMLResource.Factory.INSTANCE);

  // Get one of the standard profiles to build a jar path 
  final URL url = ClassLoader.getSystemResource("profiles/UML2.profile.uml");
  if(url == null) {
    throw new RuntimeException("Could not load 'profiles/UML2.profile.uml' from class path");
  }

  // Need the jarfile path so chop off the file specific stuff
  final String path = url.toExternalForm().split("!")[0] + "!/";

  // Build a uri for this path
  final URI baseURI = URI.createURI(path);


  // Build mappings from 'pathmap://UML_PROFILES' (or metamodels or libraries) to the point at the jarfile path
  final Map<URI,URI> uriMap = rset.getURIConverter().getURIMap();
  // pathmap://UML_PROFILES
  uriMap.put(URI.createURI(UMLResource.LIBRARIES_PATHMAP), baseURI.appendSegment("libraries").appendSegment(""));
  // pathmap://UML_LIBRARIES
  uriMap.put(URI.createURI(UMLResource.METAMODELS_PATHMAP), baseURI.appendSegment("metamodels").appendSegment(""));
  // pathmap://UML_PROFILES
  uriMap.put(URI.createURI(UMLResource.PROFILES_PATHMAP), baseURI.appendSegment("profiles").appendSegment(""));
}

// Load the test profile
Profile test = null;
{
  final URL url = ClassLoader.getSystemResource("profiles/test.profile.uml");
  if(url == null) {
    throw new RuntimeException("Could not load 'profiles/test.profile.uml' from class path");
  }

  final Resource r = rset.createResource(URI.createURI(url.toExternalForm()));

  r.load(null);

  test = (Profile)EcoreUtil.getObjectByType(r.getContents(), UMLPackage.Literals.PROFILE);
  if(test == null) {
    throw new RuntimeException("Could not load 'profiles/test.profile.uml'");
  }
}

Stereotype A = test.getOwnedStereotype("A");
Stereotype B = test.getOwnedStereotype("B");

Model m = UMLFactory.eINSTANCE.createModel();

org.eclipse.uml2.uml.Package pkg = m.createNestedPackage("pkg");

org.eclipse.uml2.uml.Class c1 = pkg.createOwnedClass("c1", false);
org.eclipse.uml2.uml.Class c2 = pkg.createOwnedClass("c2", false);

pkg.applyProfile(test);

c1.applyStereotype(A);
c2.applyStereotype(B); // throws IllegalArgumentException
