Just reviewed the bundles:
net.refractions.udig.jai and net.refractions.udig.jai.macosx

What I assume what the fragments for, please correct me, if I'm wrong:
- if jai and imageio are not in the classpath - (JaiInstallerBootstrap
-> ClassNotFoundException check) it tries to copy libraries into
possible folders (platform dependent -> therefor a mac fragment and
one for all others)
- after copying the application will restart
(PlatformUI.getWorkbench().restart()) and the libraries should be in
the classpath if everything is going right.

Right now I would say, that this would not be required anymore if we
ship udig with the JAI/ImageIO bundles and its relevant platform
dependent fragments. In addition to that we could kick out the
duplicated jar files and the partly duplicated code (of this two
fragments) as well. I've now idea how this would work in a restricted
environment, where the user can't install software and hasn't the
right to do its (administrator in windows systems)... Interesting

Any opinions?
