Hi,

using JDK 1.5.0_04 I try to read a PNG image with ImageIO.read():

String uri = "http://www.w3.org/Icons/right.png";
//String uri = "http://www.w3.org/Icons/w3c_home.png";
try
{
     InputStream inputStream = new URL(uri).openStream();
     BufferedImage bufferedImage = ImageIO.read(inputStream);
}
catch (Exception e)
{
     e.printStackTrace();
}

I get the following exception:
java.lang.IllegalArgumentException: LUT has improper length!

    at ImageIOTest.main(ImageIOTest.java:26)

When I read the other file (http://www.w3.org/Icons/w3c_home.png)
everything is fine. Is this a problem with the PNGImageReader or with
the PNG image itself? Various image viewing programs can handle the image.
