Question

当我开始游戏时，我会间歇性地出现这个错误：

Exception in thread "main" java.lang.InternalError: couldn't create component peer

我无法重现它，它似乎只是在我开始游戏时随机发生 - 有时，它开始很好，有时，它有错误。

我使用此代码启动显示：

private void setUpDisplay() {
    //System.setProperty("org.lwjgl.librarypath", new File("D:/Downloads/mcp/ship/Ship/lib/natives-win").getAbsolutePath());
    try {
        DisplayMode displayMode = null;
        DisplayMode[] modes = Display.getAvailableDisplayModes();

         for (int i = 0; i < modes.length; i++)
         {
             if (modes[i].isFullscreenCapable())
               {
                    displayMode = modes[i];
               }
         }
         if (displayMode == null){
             displayMode = new DisplayMode(100, 100);
         }
         displayMode = Display.getDesktopDisplayMode();
         //Display.setDisplayModeAndFullscreen(new DisplayMode(200, 200));
        //Display.setDisplayMode(new DisplayMode(WINDOW_DIMENSIONS[0], WINDOW_DIMENSIONS[1]));
         Display.setDisplayMode(displayMode);
        Display.setResizable(true);
        Display.setTitle("Pirate game");
        //Display.setFullscreen(true);
        try {Thread.sleep(3000);} catch (InterruptedException e1) {}

        frame = new JFrame();

        Canvas canvas = new Canvas();
        frame.add(canvas);
        frame.setSize(500, 500);
        frame.setVisible(true);
        try {
            try {Thread.sleep(3000);} catch (InterruptedException e1) {}
            Display.setParent(canvas);

            Display.create();

        } catch (LWJGLException e) {
            e.printStackTrace();
        }
        try {Thread.sleep(3000);} catch (InterruptedException e1) {}
        frame.setVisible(true);
        frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
        frame.repaint();

    } catch (LWJGLException e) {
        e.printStackTrace();
        //cleanUp(true);
    }
}

显然它与正在创建的JFrame有关（因为如果我在没有JFrame的情况下显示它工作正常），但是我目前无法解决问题（没有放弃JFrame，我可以＆＃t; t做）。

我不确定该问题是否与LWJGL / OpenGL有关，所以无论如何我都将其标记为。

此问题的最可能原因：Windows拒绝创建新窗口，因为达到了最大窗口数。
