SwingWorker mysteriously stops at 100

Hi,

Below is the class which I'm using for SwingWorker. As you can see,
the while loop is set to run while i_Ctr is less than 1500, or is
interrupted by a button action, which sets isCancelled to true.
Despite this, the counter always stops at 100. Any ideas what could
be causing this?

class SwingWorkerTask extends SwingWorker<Integer, Integer>
{
    int i_Delay = 1000;
    int i_Ctr = 0;
    int i_Count = 1500;
    boolean bPause = false;

    public void setDelay(int iDelay)
    {
        i_Delay = iDelay;
    }

    public void setCtr(int iNewCtrValue)
    {
        i_Ctr = iNewCtrValue;
    }

    public void pauseCtr()
    {
        bPause = true;
    }

    public void unpauseCtr()
    {
        bPause = false;
    }

    @Override
    protected Integer doInBackground() throws Exception
    {
        while (!isCancelled() && i_Ctr < i_Count)
        {
            i_Ctr++;
            //publish(new Integer[] { i_Ctr });
            publish(new Integer[] { i_Ctr, i_Count });
            setProgress(i_Ctr);//
            if (!bPause)
            {
                Thread.sleep(i_Delay);
            }
            else
            {
                Thread.sleep(10000);
            }
        }
        return 1;
    }
    protected void process(List<Integer> chunks)
    {
          System.out.println(chunks);
    }

}
