Get java.lang.IllegalThreadStateException in windows

Question

Hello I got this error java.lang.IllegalThreadStateException.
The whole program works under Linux now I tried it in windows almost everything works only this thread doesn't.
I found out what it was but was wondering why it is.
//Thread
       System.out.println("Tabrows " +tabrows);
       for(int i=0;i<100;i++)
       count+=0.01;
       String ja=""+form.format(count);
//       System.out.println("FORM "+ja);
       String nee =""+form.format(loop1);
//       System.out.println("count "+ja+" LOOP  "+nee);
       if (ja.equals(nee))
       slaap(10);
       draw(g,10);
       loop1=loop1+loopbuf1;
       System.out.println("GELIJK "+" loop1 count "+count+" loopbuf "+loopbuf1+" count "+ja+" LOOP  "+nee);
      public void draw(Graphics g, int x)
      System.out.println("This is a test "+x);
      progbar.ga();
//      progbar.start();
      repaint();
      }It is because of this line
progbar.start();
Can someone tell me why this doesn't work in windows and works in Linux?

What class is your progbar? If it extends Thread, you are getting a problem because you can't start the same thread more than once. In your code, it would be started (or attempted to be started) every time the window redraws.
I don't know why it would work on Linux.
