I have Jpeg2000 images with GeoTIFF headers in them.  I've been monkeying
with the JAI ImageIO library which has Jpeg2000 support to get at the UUID
metadata box and then using the data there to get the TIFF image which
contains the right metadata.  I noticed that in Geotools there is a "jp2kak"
module but it is based on Kakadu (non-Java native code), not Sun's pure-Java
implementation available here: https://jai-imageio.dev.java.net/.  Can
someone tell me what the status of this geotools module is and why it uses
Kakadu instead of Sun's code?

By the way, I did have to use Sun's latest 1.2 from source control because
there was a bug fix in there that is not in 1.1 resulting in NPEs.
