WebView load url not working

I have a Swing application with a JavaFX WebView embedded in it. I can load an initial web page using the WebView's WebEngine. However, subsequent calls to WebEngine.load are not working for some reason. Here's the debugging code I've added to the WebEngine:

private static WebView initFX(JFXPanel fxPanel) {
    StackPane root = new StackPane();
    Scene scene = new Scene(root, Color.ALICEBLUE);

    final WebView webView = new WebView();
    final WebEngine webEngine = webView.getEngine();
    root.getChildren().add(webView);

    webEngine.load("http://www.google.com");

    webEngine.setOnAlert(new EventHandler<WebEvent<String>>() {
        @Override
        public void handle(WebEvent<String> arg0) {
            System.out.println("alert: " + arg0);
        }
    });

    webEngine.getLoadWorker().progressProperty().addListener(new ChangeListener<Number>() {
        @Override
        public void changed(ObservableValue<? extends Number> arg0, Number arg1, Number arg2) {
            System.out.println("Process changed: " + arg0 + ", arg1: " + arg1 + ", arg2: " + arg2);
        }
    });

    webEngine.getLoadWorker().messageProperty().addListener(new ChangeListener<String>() {
        @Override
        public void changed(ObservableValue<? extends String> arg0, String arg1, String arg2) {
            System.out.println("message changed: " + arg0 + ", arg1: " + arg1 + ", arg2: " + arg2);
        }
    });

    webEngine.getLoadWorker().exceptionProperty().addListener(new ChangeListener<Throwable>() {
        @Override
        public void changed(ObservableValue<? extends Throwable> arg0, Throwable arg1, Throwable arg2) {
            throw Throwables.throwUncheckedException(arg2);
        }
    });

    webEngine.getLoadWorker().stateProperty().addListener(new ChangeListener<Worker.State>() {
        @Override
        public void changed(ObservableValue<? extends Worker.State> arg0, Worker.State arg1, Worker.State arg2) {
            System.out.println("old state: " + arg1 + ", new state: " + arg2 + ", arg0: " + arg0);
        }
    });

    fxPanel.setScene(scene);
    return webView;
}

And then we have the code that tries to change the web page:

// Drag and drop event comes in on the AWT thread.
// Switch to the FX thread and run the load there
public void dropObjects(Iterable<Locator> objects) {
    try {
        browserControllerLatch.await();
        Platform.runLater(new Runnable() {
            @Override
            public void run() {
                webView.getEngine().load("http://www.arstechnica.com");
            }
        });
    } catch (InterruptedException e) {
        throw Throwables.throwUncheckedException(e);
    }
}

This produces the following output. I first load google, and then try to load the nytimes.com.

From the output, it seems like the WebView has loaded nytimes.com. However, the WebView never shows the update.

Does anyone have ideas about what might be wrong, or suggestions for how I can get more information about what's going on within the WebView?

I see the same behavior in Java 7 and 8.

Edit: If anyone has requests for additional info or debugging output, I'm happy to provide that.

Edit: This was caused by a mistake in other code not related to the JavaFX/Swing integration. Thank you all for your suggestions!

Here's a fully working example about how to do it. In the future please post a MCVE, especially since you got Swing involved and posted only some parts of JavaFX code.

import java.awt.BorderLayout;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javafx.application.Platform;
import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.concurrent.Worker;
import javafx.embed.swing.JFXPanel;
import javafx.scene.Scene;
import javafx.scene.layout.BorderPane;
import javafx.scene.web.WebEngine;
import javafx.scene.web.WebView;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;

public class SwingBrowser extends JPanel {

    WebEngine webEngine;

    private static void initAndShowGUI() {

        JFrame frame = new JFrame();

        frame.add(new SwingBrowser());
        frame.setSize(1024, 768);
        frame.setVisible(true);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    }

    public SwingBrowser() {

        JPanel toolbar = new JPanel();
        toolbar.setLayout(new FlowLayout());

        JButton button;

        button = new JButton("Google");
        button.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {

                loadPage("http://www.google.com");
            }
        });

        toolbar.add(button);

        button = new JButton("NY Times");
        button.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {

                loadPage("http://www.nytimes.com");
            }
        });

        toolbar.add(button);

        final JFXPanel fxPanel = new JFXPanel();

        setLayout(new BorderLayout());
        add(fxPanel, BorderLayout.CENTER);
        add(toolbar, BorderLayout.NORTH);

        Platform.runLater(new Runnable() {
            @Override
            public void run() {
                initFX(fxPanel);
            }
        });
    }

    private void loadPage(String url) {

        Platform.runLater(new Runnable() {
            @Override
            public void run() {

                webEngine.load(url);

            }
        });

    }

    private void initFX(JFXPanel fxPanel) {
        Scene scene = createScene();
        fxPanel.setScene(scene);
    }

    private Scene createScene() {

        WebView webView = new WebView();

        webEngine = webView.getEngine();

        webEngine.getLoadWorker().progressProperty().addListener(new ChangeListener<Number>() {
            @Override
            public void changed(ObservableValue<? extends Number> arg0, Number arg1, Number arg2) {
                System.out.println("Process changed: " + arg0 + ", arg1: " + arg1 + ", arg2: " + arg2);
            }
        });

        webEngine.getLoadWorker().messageProperty().addListener(new ChangeListener<String>() {
            @Override
            public void changed(ObservableValue<? extends String> arg0, String arg1, String arg2) {
                System.out.println("message changed: " + arg0 + ", arg1: " + arg1 + ", arg2: " + arg2);
            }
        });

        webEngine.getLoadWorker().exceptionProperty().addListener(new ChangeListener<Throwable>() {
            @Override
            public void changed(ObservableValue<? extends Throwable> arg0, Throwable arg1, Throwable arg2) {
                System.out.println(arg0);
                System.out.println(arg1);
                System.out.println(arg2);
            }
        });

        webEngine.getLoadWorker().stateProperty().addListener(new ChangeListener<Worker.State>() {
            @Override
            public void changed(ObservableValue<? extends Worker.State> arg0, Worker.State arg1, Worker.State arg2) {
                System.out.println("old state: " + arg1 + ", new state: " + arg2 + ", arg0: " + arg0);
            }
        });

        webEngine.load("http://www.google.com");

        BorderPane bp = new BorderPane();

        bp.setCenter(webView);

        Scene scene = new Scene(bp);

        return (scene);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                initAndShowGUI();
            }
        });
    }
}
