對於JPanel TitledBorder沒有蝕刻的框架

Question

我在JFrame上使用JPanel，我在JPanel上有一個標題爲。我創建了JPanel，標題邊界爲NetBeans，我可以看到我的標題和蝕刻幀。當我跑步時，我只看到標題，但看不到蝕刻的框架。任何想法爲什麼我看不到蝕刻的框架？我嘗試設置外觀和感覺，但不能讓框架顯示出來，看起來很奇怪，沒有邊框的標題。

運行爪哇1.7在Windows 7。當我們使用java 1.6時，我不記得發生了這種情況。

這裏的示例代碼：

public class NewJFrame extends javax.swing.JFrame { 

/** Creates new form NewJFrame */

Answer 1

這不是一個答案了

這是我得到1.7：

難道不是你想要的？

編輯：

嘗試運行此：

public class NewJFrame extends JFrame { 

    public NewJFrame() { 

     JPanel p = new JPanel(); 
     p.add(new JLabel("AAAAA")); 
     p.setBorder(BorderFactory.createTitledBorder("Title")); 
     add(p); 
     setLocationRelativeTo(null); 
     setDefaultCloseOperation(EXIT_ON_CLOSE); 
     pack(); 
     setVisible(true); 
    } 

    public static void main(String args[]) { 

     new NewJFrame(); 
    } 
} 

這是非常小的，應縮小選擇範圍。這就是我得到：
