Easy does it - don't want to mess up other apps. 

One small danger is for apps that include their own copy of jai. So not want conflicts with jre copy. 

Also need to test image io ext - gdal libs need to be on jre library path. 

Easiest done with links in jre/bin but perhaps other options available. Finally you may be able to configure some of these by updating udig_internal.ini or making change to script that starts udig and have less of an impact on other projects. 

Excellent work frank!
