Windows Server 2003 中的 Java swing 错误

Question

我面临一个奇怪的问题，似乎组合框的 PropertyChange 事件在 Windows Server 2003 中没有被触发。我已经在 J​​ava Swing 中创建了该应用程序。当我在其他操作系统上运行该应用程序时，它似乎工作正常。

任何帮助将不胜感激。

只是我的好奇心，这段代码适用于 WinXP/Win2003 和 Win7/Win2008 各种 JRE6_XX_XXX，您能否将您的 JComboBox 解决方法放在那里

import java.awt.*;
import java.awt.event.*;
import java.beans.*;
import javax.swing.*;

public class TestPropListener {

    private static final Color TRUE_COLOR = new Color(180, 200, 255);
    protected static final Color FALSE_COLOR = new Color(255, 100, 100);

    private static void createAndShowUI() {
        final MyBean panel = new MyBean();
        panel.setTitle(true);
        //panel.setPreferredSize(new Dimension(400, 400));
        panel.setBackground(TRUE_COLOR);
        panel.addMouseListener(new MouseAdapter() {

            @Override
            public void mousePressed(MouseEvent e) {
                panel.setTitle(!panel.getTitle());
            }
        });
        panel.addPropertyChangeListener(new PropertyChangeListener() {

            @Override
            public void propertyChange(PropertyChangeEvent evt) {
                if (evt.getPropertyName().equals(MyBean.TITLE_PROP_NAME)) {
                    panel.setBackground(panel.getTitle() ? TRUE_COLOR : FALSE_COLOR);
                }
            }
        });
        JFrame frame = new JFrame("Test Property Listener");
        frame.getContentPane().add(panel);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(400,300);
        //frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        java.awt.EventQueue.invokeLater(new Runnable() {

            @Override
            public void run() {
                createAndShowUI();
            }
        });
    }

    private TestPropListener() {
    }
}

class MyBean extends JPanel {

    public final static String TITLE_PROP_NAME = "title";
    private static final long serialVersionUID = 1L;
    private boolean title;
    private final PropertyChangeSupport pcs = new PropertyChangeSupport(this);

    public boolean getTitle() {
        return this.title;
    }

    public void setTitle(boolean title) {
        boolean old = this.title;
        this.title = title;
        this.pcs.firePropertyChange(TITLE_PROP_NAME, old, title);
    }

    @Override
    public void addPropertyChangeListener(PropertyChangeListener listener) {
        this.pcs.addPropertyChangeListener(listener);
    }

    @Override
    public void removePropertyChangeListener(PropertyChangeListener listener) {
        this.pcs.removePropertyChangeListener(listener);
    }
}
