Hi Dalibor, I think the problem is in the thread library:
kaffe was compiled with standard thread library (pthread);
I tried to compile with the jthread library (--with-unix-jthreads)
and the initialization always complete correctly.
By the way, with pthreads, when the initialization was correct needed
30seconds, now it needs 10 seconds.

Now I'm testing programs behaviour, starting from helloworld:

import java.awt.*;

public class Hello extends Frame {
    public static void main(String argv[])
    {
	new Hello();
    }
    
    public Hello() {
	super("Hello World!");
	Label hello = new Label("Hello World");

	// bring it under geometry control
	add("Center", hello);
	resize(500, 500);

	// map the widgets
	show();
    }
}

this works correctly on PC, while on Nano-X do not display
the label in the window (the window appears, but is empty)
The window title string on the contrary is shown correctly.
Now I'm  investigating about this :-(

Thanks so far
bye
