I moved the jai binaries and jars into a custom folder under udig.
Then I added this line on start of udig.sh, right under the gdal line:

export LD_LIBRARY_PATH=LD_LIBRARY_PATH:/usr/lib/udig/jai/ext/

I did not touch either ImageIO or GDAL, since udig seemed to open every 
file I tested just with JAI moved around.
