一个简单的例子无法运行，有手机3D开发经验的朋友请指点一下是什么问题

//public class FrameWork extends FullCanvas implements Runnable
public class FrameWork extends Canvas implements Runnable
{
private Main main;
private Display display;

public static boolean bRunning;
public static int iWidth;
public static int iHeight;


public FrameWork(Main main, Display display)
{
this.main = main;
this.display = display;

bRunning = true;
bFirstInit = true;
iWidth = getWidth();
iHeight = getHeight();

loadAll();
}

public void run()
{
while (bRunning)
{
Main.sleep(1000);
update();
}
}

private Graphics3D g3d;
private World world;
private Camera camera;
public void loadAll()
{
try
{
Object3D[] objList = Loader.load("/map.m3g");
g3d = Graphics3D.getInstance();

for (int i=0; i<objList.length; ++i)
{
if (objList[i] instanceof World)
{
world = (World) objList[i];
break;
}
}

objList = null;
}
catch (Exception e)
{
//
}
}

public void update()
{
repaint();
}

public void paint(Graphics g)
{

g3d.bindTarget(g);
g3d.render(world);
g3d.releaseTarget();

// System.gc();
}
}

我用的是索爱K750模拟器，报的错为：
Error condition -1 on socket 4920
Windows error code 10055

请帮忙分析下是什么问题，谢谢！！！
