Try out image4j - Image Library for Java
The image4j library allows you to read and write certain image formats in 100% pure Java.
Currently the following formats are supported:
- BMP (Microsoft bitmap format - uncompressed; 1, 4, 8, 24 and 32 bit)
- ICO (Microsoft icon format - 1, 4, 8, 24 and 32 bit [XP uncompressed, Vista compressed])
With the library you can easily decode your ico file
List<BufferedImage> image = ICODecoder.read(new File("input.ico"));

Apache Commons Imaging allows to read and write ICO files:
List<BufferedImage> images = Imaging.getAllBufferedImages(new File("input.ico"));
It supports several popular formats of metadata too (EXIF, IPTC and XMP).
TwelveMonkeys ImageIO allows to extend the ImageIO API to support ICO and numerous other image file formats.
