A DESCRIPTION OF THE PROBLEM :
Pressing Ctrl+Z in a TextInputControl bound to a property (and the property bound back to TextInputControl.textProperty()) leads to:

Exception in thread "JavaFX Application Thread" java.lang.NullPointerException: Cannot read field "next" because "this.undoChange" is null
        at javafx.controls@22.0.1/javafx.scene.control.TextInputControl.updateUndoRedoState(TextInputControl.java:1250)

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a TextField. Create a separate SimpleStringProperty. Bind a change of TextField.textProperty() to SimpleStringProperty.set() and vice versa. Start the application. Type something in the field. Press Ctrl+Z. See an NPE:

Java:

        TextField textField = new TextField();
        textField.setPromptText("Type something and then press Ctrl+Z.");
        vbox.getChildren().add(textField);
        SimpleStringProperty textProperty = new SimpleStringProperty();
        textProperty.addListener((_, _, newValue) -> textField.textProperty().set(newValue));
        textField.textProperty().addListener((_, _, newValue) -> textProperty.set(newValue));



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Undo is executed.

CUSTOMER SUBMITTED WORKAROUND :
        textInputControl.addEventFilter(KeyEvent.ANY, e -> {
            if (e.getEventType() == KeyEvent.KEY_PRESSED && e.isShortcutDown()) {
				switch (e.getCode()) {
                    case Y -> {
                        redoAction.execute();
                        e.consume();
                    }
                    case Z -> {
                        undoAction.execute();
                        e.consume();
