Hi,

The Kakadu driver can create float rasters and compress 16bits rasters 
lossless, so this line in the driver sources should be updated :

         poDriver->SetMetadataItem( GDAL_DMD_CREATIONDATATYPES,
                                    "Byte Int16 UInt16" );

and also the driver documentation (http://gdal.maptools.org/frmt_jp2kak.html) :

"... When reading images this driver will represent the bands as being Byte 
(8bit unsigned), 16 bit signed or 16 bit unsigned.
...
NOTE: QUALITY=100 will not be lossless for 16bit images."


Regards,

Julien
