Seems it is not supported currently, I tried the code below then the child is under the second (last) parent.

public TreeModel<DefaultTreeNode<String>> getModel () {
    List children = new ArrayList();
    children.add(new DefaultTreeNode("child", (List)null));
    DefaultTreeNode root = new DefaultTreeNode(null,
            new DefaultTreeNode[] {
                new DefaultTreeNode("aaa", children),
                new DefaultTreeNode("bbb", children)
    });
    if (_model == null) {
        _model = new DefaultTreeModel<String>(root);
    }
    return _model;
}

A node allows multiple parents is more like a graph rather than a tree, maybe you can post a feature request.
