I am facing a issue using Newts GLWindow painting to FBO.

To help validate the issue I made a simple application to reproduce the problem:

public static GLWindow window;
public static Animator animator;
   
    public static void main( String[] args )
    {
//        ExecutorService pool = Executors.newFixedThreadPool(Runtime.getRuntime().availableProcessors() * 2);
//        pool.execute(new WorkerThread());
        GLProfile glp = GLProfile.getDefault();
        GLCapabilities caps = new GLCapabilities(glp);
        caps.setBackgroundOpaque(false);
        caps.setOnscreen(false);

        window = GLWindow.create(caps);
        animator = new Animator(window);

        //Size is purposely big to make exception be thrown
        window.setSize(40000, 40000);
        window.setVisible(true);
       
        System.out.println("TEST2");
    }

If I execute this simple code in the main Thread, the exception is thrown as expected.
However, if I run the same code inside a thread (uncomment the first two lines of the main, creating a WorkerThread class with the same code), the application enters an infinite loop in the jogamp.newt.DefaultEDTUtil class, precisely in the line 347 of the run() method.

Is this a bug in the API implementation, or is there a way to force this thread to exit?
