[udig-devel] tif render error.

[Vince Darley]

We seem to have resolved this by using -Dosgi.parentClassloader=ext

Somehow that piece of information was not readily accessible by 
googling for errors related to jai.

There may well still be some projection issues perhaps.  We'll have 
to try to pick the right projection, I suppose for best results with rasters.

Vince.
