I have a program that makes use of the following method to get a scaled instance of an image icon:

public ImageIcon createScaledImageIcon(String filename) {
    ImageIcon icon = new ImageIcon(filename);
    Image image = icon.getImage().getScaledInstance(cardWidth, cardHeight, Image.SCALE_SMOOTH);
    icon.setImage(image);
    return icon;
}

I don't know if it's the source of the problem or not. But i get the following error messages:

Exception in thread "Image Fetcher 0" java.lang.UnsatisfiedLinkError: sun.awt.image.ImageRepresentation.setBytePixels(IIII[BIILsun/awt/image/ByteComponentRaster;I)V at sun.awt.image.ImageRepresentation.setBytePixels(Native Method)

at sun.awt.image.ImageRepresenation.setPixels(Unknown Source)

at sun.awt.image.ImageDecoder.setPixels(Unknown Source)

at sun.awt.image.GIFImageDecoder.sendPixels(Unknown Source) ...

Let me know if there is any other information I could include that might be of use.
