构造JFrame时Java Web Start挂起

Question

使用Java Web Start启动程序时需要帮助。

我从主页启动程序，该程序只是在进程处理程序中与javaw-process一起挂起。 当我使用jvisualvm转储线程时，我看到它挂在“ AWT-EventQueue-0”线程中（在构造我的JFrame时）：

"AWT-EventQueue-0" prio=6 tid=0x02da7c00 nid=0x1414 runnable [0x0367f000]
    java.lang.Thread.State: RUNNABLE
        at sun.awt.windows.WToolkit.getScreenInsets(Native Method)
        at sun.awt.windows.WToolkit.getScreenInsets(Unknown Source)
        at java.awt.Window.init(Unknown Source)
        at java.awt.Window.<init>(Unknown Source)
        at java.awt.Frame.<init>(Unknown Source)
        at javax.swing.JFrame.<init>(Unknown Source)
        at se.testing.Application$2.run(Application.java:170)
        at java.awt.event.InvocationEvent.dispatch(Unknown Source)
        at java.awt.EventQueue.dispatchEvent(Unknown Source)
        at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source)
        at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source)

这是主要的样子：

public static void main(String... args) {

    ....

    SwingUtilities.invokeLater(new Runnable() {
        public void run() {
            JFrame f = new JFrame("Test");
            ...
        }
    });
}

更新 ：这是jnlp文件：

<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="6.0+" 
      codebase="http://localhost/archive/Application-1.0.0/"
      href="application.jnlp">

    <jar href="wsdl4j-1.6.2.jar"/>
  </resources>
  <application-desc main-class="se.testing.Application">
  </application-desc>
</jnlp>

有什么问题吗？ （这是我触摸GUI的第一位，并且我在Windows XP上。）

另外，我注意到我还有另一个AWT线程（??！？！）也挂在不同的地方：

从运行1开始，我将其挂在这里：

从运行2：

Answer 1

尝试设置f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

Answer 2

如果有人找到其他解决方案，我直接接受！ 我不鄙视当前的解决方案...

---

看来只有在使用Intel HD Graphics（我的系统是Core i3 clarkdale）时才会发生。

可能的解决方案（已测试！）：

• 使用Windows默认驱动程序（〜vga驱动程序）
• 新显卡

Answer 3

当然，图形驱动程序和Java似乎存在某种问题。

查看此指向Java 2D系统设置的链接是否有帮助。

Answer 4

您是否尝试过在主线程中构造GUI？ 事件处理线程是否为-处理事件:-)

Answer 5

试试这个代码：

public static void main(String... args) {
    JFrame f = new JFrame("Test");
    f.setVisible( true );
}
