Buggy source:

Fixed version (ground truth):

  FolderTreeNode curNode;
  if (rootObj instanceof FolderTreeNode) {

  }
 else   throw new RuntimeException("String_Node_Str" + rootObj.getClass());
  LinkedList<Record<A>> dirStack=new LinkedList<Record<A>>();
  TreePath treePath=new TreePath(curNode);
  for (  String currentComponent : pathnameComponents) {
    dirStack.addLast(curNode.getRecordContainer().getRecord(genericPlaceholder));
    populateTreeNodeFromPath(curNode,dirStack);
    dirTree.expandPath(treePath);
    int childCount=treeModel.getChildCount(curNode);
    FolderTreeNode requestedNode=null;
    for (int i=0; i < childCount; ++i) {

        if (rec.getName().equals(currentComponent)) {

          break;
        }
