我想我知道发生了什么事。如果将main（）方法放在 另一个类中 ，则一切正常。因此，您需要类似：

public class RootGUILauncher {  public static void main(String[] args) {    try {     System.setProperty("apple.laf.useScreenMenuBar", "true");     System.setProperty("com.apple.mrj.application.apple.menu.about.name", "Test");     UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());        }        catch(ClassNotFoundException e) {     System.out.println("ClassNotFoundException: " + e.getMessage());        }        catch(InstantiationException e) {     System.out.println("InstantiationException: " + e.getMessage());        }        catch(IllegalAccessException e) {     System.out.println("IllegalAccessException: " + e.getMessage());        }        catch(UnsupportedLookAndFeelException e) {     System.out.println("UnsupportedLookAndFeelException: " + e.getMessage());        }        javax.swing.SwingUtilities.invokeLater(new Runnable() {        public void run() { new RootGUI();        }    });}

然后将您的RootGUI类放在另一个文件中。
