构造JFrame时Java Web Start挂起

Question

I need help when starting my program with Java Web Start.

I start my program from the homepage the program just hangs with a javaw-process in the process handler. When I dump the threads, using jvisualvm, I see that it hung in the "AWT-EventQueue-0" thread (when constructing my JFrame):

"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.EventDispatchThread.pumpOneEventForFilters(Unknown Source)
        at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source)

Here is what the main looks like:

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

    ....

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

Update : And here is the jnlp file:

What could be wrong?! (It is the first place I touch the GUI and I'm on Windows XP.)

Also, I noticed that I have another AWT thread (??!?!) also hanging at different places:

From run 1 I got it to hang here:

Answer 1

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

Answer 2

If someone finds another solution I accept it directly! I'm not contempt with the current solution...

---

It seems that it only happens when using Intel HD Graphics (my system is Core i3 clarkdale).

Possible solutions are (tested!):

• Using windows default drivers (~vga drivers)
• New graphic card

Answer 3

Certainly seems like some kind of problem with the graphics drivers and java.

See if this link to Java 2D system settings helps.

Answer 4

Have you tried constructing the GUI in the main thread? The event handling thread if for - handling events :-)

Answer 5

Try this code:

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