Bug 42352

I wrote some code
       final TIFFRenderer render = new TIFFRenderer() {
          protected BufferedImage getBufferedImage(int w, int h) {
            return new BufferedImage(w, h, BufferedImage.TYPE_BYTE_GRAY);
          }
        };
        render.setUserAgent(userAgent);
        userAgent.setRendererOverride(render);

... and try exception
