When sorting a TreeTableView, after the sorted content has been cleared, an IndexOutOfBoundsException is thrown.

The following code snippet reproduces the issue:

    @Override
    public void start(Stage stage) {
        TreeTableView<String> treeTableView = new TreeTableView<>();
        TreeTableColumn<String, String> treeTableColumn1 = new TreeTableColumn<>("Name");
        treeTableColumn1.setCellValueFactory(p -> new SimpleStringProperty(p.getValue().getValue()));
        treeTableView.getColumns().add(treeTableColumn1);
        TreeItem<String> item1 = new TreeItem<>("Joe");
        TreeItem<String> root = new TreeItem<>("root");
        root.getChildren().add(item1);
        treeTableView.setRoot(root);
        treeTableView.setShowRoot(false);

        Scene scene = new Scene(treeTableView, 640, 480);
        stage.setScene(scene);
        stage.show();

        // 1. select
        treeTableView.getSelectionModel().select(0);

        // 2. sort
        treeTableView.getSortOrder().add(treeTableColumn1);
        treeTableView.sort();

        // 3. clear
        root.getChildren().clear();

        // 4. sort again
        treeTableView.sort(); // <-- This causes the exception
    }

Throws:
