This issue was found on analysing the ignored Spinner test as part of JDK-8328667
Listener added to valueProperty of the spinner is not invoked on changing the spinner value using getEditor().setText() method.

Steps to reproduce the issue:
Run the source code given below.
Notice that the spinner value displayed on console is 5 where as the value displayed in Spinner is 3.
On changing the value manually using spinner, it changes from 5 instead of 3.

-----BEGIN SOURCE-----
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.*;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;


public class SpinnerSample extends Application {
    int count = 0;

    public void start(Stage stage) {
        Spinner<Integer> spinner = new Spinner<>(0, 10, 5, 1);
        spinner.valueProperty().addListener(o -> {
            System.out.println("Listener invoked");
            System.out.println((int)spinner.getValue());
            count++;
        });
        spinner.getEditor().setText("3");

        System.out.println(count);
        System.out.println((int)spinner.getValue());

        VBox vBox = new VBox(spinner);

        Scene scene = new Scene(vBox, 400, 200);
        stage.setScene(scene);
        stage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }

}
