Wa, wa, wa, wait! Some of JTextComponent methods are thread safe. Your
original code should run normally as is. Try this:

Good point. OTOH, I think this problem *might* be
better suited to a progress bar (which would require
accounting for the 'update on EDT'). Try doing this
using AWT!

<sscce>
import java.awt.BorderLayout;
import javax.swing.*;

public class SwingProgress {

public static void main(String[] args) throws Exception {

   JFrame frame = new JFrame();
   frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   int num = 1000;
   JProgressBar pb = new JProgressBar(0,num);
   pb.setStringPainted(true);
   frame.getContentPane().add(pb, BorderLayout.CENTER);
   frame.pack();
   frame.setVisible(true);

   for( int i =0; i<=num; i++){
     Thread.sleep(5);
     pb.setValue(i);
   }
   System.out.println("Finished");
}
}
</sscce>
