Ohh, the way you were talking it sounded like the top
was empty and you had replaced it's paint method...

The Source code? There really isn't much to know...

Don't call repaint this should lead to an infinite loop.
If your list of shapes changes you will need to trigger a
repaint of the canvas, it will then call your overlay to paint...

It is called whenever the canvas is painted - if the canvas has an
offscreen image (i.e. it is rendering an SVG document), which from your
earlier talk I'm guessing your top Canvas doesn't. I would lean towards
considering this behavior a bug (it's easy to fix, move the loop at the
end
of batik.swing.gvt.JGVTComponent.paintComponent outside the check if the
image is null).
