Java Swing JWindow应用程序崩溃
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resize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; 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; } } 我还没有发现其他有关此问题的投诉，并且尚未在oracle网站上发布错误。 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。
有没有其他人遇到这个问题并找到了解决方法？

您的Timer不会在Swing UI线程上调度Swing UI事件。 你需要“invokeLater”你的runnable所以它在正确的线程上运行。
或者，您可以让计时器执行SwingWorker，使用done（）方法发布事件（保证在事件派发线程上）
