public void testCreateChange() throws OperationCanceledException,
    CoreException {
  // We're going to delete compilation unit R.java
  ICompilationUnit cu = rClass.getCompilationUnit();
  IType r = cu.getType("R");

  // Verify that the index currently contains one JSNI reference to R
  Set<IIndexedJavaRef> refs = JavaRefIndex.getInstance().findTypeReferences(
      r.getFullyQualifiedName());
  assertEquals(1, refs.size());

  // Delete R.java
  cu.delete(true, null);
  assertFalse(cu.exists());

  // Now verify that the index entries pointing to R have been purged
  refs = JavaRefIndex.getInstance().findTypeReferences(r.getElementName());
