将以下代码编译为可执行JAR时，会产生不同的结果。
在我们测试的一半计算机上，必须在内容（swing节点）显示之前移动Java FX Window。在另一半，它显示内容而不操纵窗口。所有计算机都是基于Windows的（有些是W10，有些是W7）。
JRE（1.8.0_121）打包到程序中，批处理文件将JAR指向该JRE。
HistoryWindow(Task task, Scene scene) {
history = task.getHistoryItems();
String text = "";
t = task;
sc = scene;
panel = new JPanel();
panel.setSize(new Dimension(1600,850));
panel.setLayout(new GridLayout(0,1,0,20));
panel.addMouseListener(this);
scrollPane = new JScrollPane(panel);
scrollPane.setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER);
Stage stage = new Stage();
pane = new ScrollPane();
SwingNode swingN = new SwingNode();
initAndSetPanel();//Placeholder for the setup of the JPanel added to the scrollPane
scrollPane.revalidate();
createSwingContent(swingN);
pane.setContent(swingN);
stage.setScene(new Scene(pane, 400, 850));
mystage = stage;
stage.setTitle("History window");
stage.initModality(Modality.WINDOW_MODAL);
stage.initOwner(
(scene.getWindow()));
//stage.show();
stage.showAndWait()
/* Same result as above
Platform.runLater(new Runnable() {
@Override
public void run() {
stage.showAndWait();
}
});*/
}
createSwingNode（swingNode）方法使用SwingUtilities.invokeLater创建swing节点。
private void createSwingContent(final SwingNode swingNode) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
swingNode.setContent(scrollPane);
}
});
}
代码总是运行到stage.showAndWait（）（通过print语句验证），我不确定是什么导致了结果的差异。非常感谢帮助。
如果Jpanel设置导致了差异，这里是它的代码（可以在占位符方法中插入）。另外，不要因为我没写这个代码来判断我这个代码：）
