我有需要的谷歌地图在桌面Java应用程序中嵌入一个项目。 我经过一番研究，发现的Java FX没有提供该功能，并着手编写一个示例应用程序的PoC。 应用工作，一切都很好。 升级到新7u7 Java版本后，我的代码不再工作就像它之前。 该代码运行并显示该网页，但没有手势（paning /变焦）事件被触发的网页（谷歌地图）和当我clikc某些原因和阻力（好像平移）我得到的封闭例外，我可以使无感。
我非常感激任何了解的人可能在谷歌地图中的一个JavaFX 2.2应用程序的emmbedding。 预先感谢您的任何帮助和/或建议
以下是我的应用程序代码/ HTML代码，并抛出的异常：
JavaFX代码：
private Scene scene;
private MyBrowser myBrowser;
private LocationClickHandler handler;
private Vector<Button> buttons;
//private Moderator moderator;
/**

public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) {
buttons = new Vector<Button>();
//moderator = new Moderator();
handler=new LocationClickHandler();
primaryStage.setTitle("java-buddy.blogspot.com");
myBrowser = new MyBrowser();
//moderator.registerAddIconListener(myBrowser);
VBox mainbox = new VBox();
mainbox.getChildren().add(myBrowser);
// mainbox.getChildren().add(generateEntitiesButtonBox());
// mainbox.getChildren().add(generateSensorsButtonBox());
scene = new Scene(mainbox, 1280, 760);
primaryStage.setScene(scene);
primaryStage.show();
}
class MyBrowser extends Region {
HBox toolbar;
WebView webView = new WebView();
WebEngine webEngine = webView.getEngine();
public MyBrowser(){
webView.setMinSize(1280, 400);
final URL urlGoogleMaps = getClass().getResource("googlemaps2.html");
webEngine.load(urlGoogleMaps.toExternalForm());
getChildren().add(webView);

win.setMember("java", handler);
}
}
