运行多个线程冻结Java

Question

I need to instantiate a class on a separate thread from my first one, I found this , which works, using it like this:

private class PongThread extends Thread {

    public void run() {
        new Pong(WINDOW);
    }
}

And instantiating like this:

new PongThread().start();

The problem is that if I try to instantiate it twice, then the program just stops responding. So how do I do this so that I can make a new PongThread as many times as I want?

EDIT:

My Pong class is a LWJGL Display running with a while loop and the sync(FPS) method:

while(isRunning) {

    //Logic and rendering method calls, etc.

    Display.update();
    Display.sync(30);
}

EDIT #2:

My pong class contains and uses private classes (I don't know if that might affect it)

Answer 1

Display class from LWJGL is a static class and I'm not sure if you can use it separately for different threads. Try using JOGL instead. It has more capabilities then LWJGL and it has much better support then LWJGL.
