问题描述
如果我使用JDK1.8_40或更新版本（Oracle或OpenJDK执行相同操作），以下代码和对话框调整大小将使应用程序崩溃（尝试过Windows 7，x64,64位JDK）
import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JPanel;
import javax.swing.JWindow;
import javax.swing.SwingUtilities;
import javax.swing.Timer;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
公共类Main {
public static void main（String [] args）{
SwingUtilities.invokeLater（new Runnable（）{
@Override
public void run（）{
final JDialog dialog = new JDialog（）;
dialog.add（new JPanel（））;
dialog.setVisible（true）;
dialog.setBounds（100,100,100,100）;
final JWindow dependentWindow = getjWindow（dialog）;
dependentWindow.setVisible（true）;
dependentWindow.setBounds （100,100,100,100）;
定时器t =新定时器（300，新ActionListener（）{
@Override
public void actionPerformed（ActionEvent e）{
dependentWindow .setVisible（！dependentWindow.isVisible（））;
}
}）;
t.start（）;
}
}）;
}
私有静态JWindow getjWindow（JDialog对话框）{
JWindow w = new JWindow（对话框）;
JPanel panel = new JPanel（）;
panel.add（新JButton（按钮））;
w.add（小组）;
返回w;
}
}
我还没有找到关于这个和避风港的其他投诉在oracle的网站上发布了一个错误。一个可能的解决方法是将JWindow更改为未修饰的JDialog，但这对我来说还有其他问题，所以我不会改变它。
是否有其他人遇到此问题找到了解决方法？

你的Timer没有在Swing UI上调度Swing UI事件线。你需要invokeLater你的runnable所以它在正确的线程上运行。
或者，你可以让计时器执行一个SwingWorker，并使用done（）方法发布事件（保证在事件发送线程上）
If I use JDK1.8_40 or newer (Oracle or OpenJDK do the same), the following code together with a dialog resize will crash the application (tried Windows 7, x64, 64bit JDK)
import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JPanel;
import javax.swing.JWindow;
import javax.swing.SwingUtilities;
import javax.swing.Timer;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class Main {
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
final JDialog dialog = new JDialog();
dialog.add(new JPanel());
dialog.setVisible(true);
dialog.setBounds(100, 100, 100, 100);
final JWindow dependentWindow = getjWindow(dialog);
dependentWindow.setVisible(true);
dependentWindow.setBounds(100, 100, 100, 100);
Timer t = new Timer(300, new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
dependentWindow.setVisible(!dependentWindow.isVisible());
}
});
t.start();
}
});
}
private static JWindow getjWindow(JDialog dialog) {
JWindow w = new JWindow(dialog);
JPanel panel = new JPanel();
panel.add(new JButton("button"));
w.add(panel);
return w;
}
}
I haven't found other complaints about this and haven't posted a bug on oracle's website yet. A possible workaround is changing the JWindow to an undecorated JDialog but that comes with other issues for me so I wouldn't change this yet.
Did anyone else hit this problem and found a workaround?

Your Timer is not dispatching the Swing UI events on the Swing UI Thread. You need to "invokeLater" your runnable so it gets ran on the right thread.
Alternatively, you could have the timer execute a SwingWorker, with the done() method posting the event (it is guaranteed to be on the event dispatch thread)
