Is there any other way besides using ImageIO.read to get image height and width?

Because I encounter an issue that locks up the thread.

This error only occurs on a Sun app server and therefore I suspect that it is a Sun bug.

Here is something very simple and handy. 

BufferedImage bimg = ImageIO.read(new File(filename));
int width          = bimg.getWidth();
int height         = bimg.getHeight();
