Hi,

to me it looks like a problem with the
  public void paint(Graphics g)
method of your viewer. Probably it does not paint the image (g.drawImage)
except on the first call, so any repaint operation will leave it white.
E.g., do you have the bufferedImage in a class variable, so that it
remains accessible in a separate (repaint) thread)?
