The fix for JDK-6788458 causes PNGImageReader to throw an ArrayIndexOutOfBoundsException reading some pngs that it previously accepted.

===
import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

public class Image {
  public static void main(String[] args) throws IOException {
    BufferedImage image = ImageIO.read(new File(args[0]));
    ImageIO.write(image, "PNG", new File(args[1]));
  }
}

$ java Image add_white.png output.png
