That sounds fine; why not just update the geotools implementation? ie we 
found something that is a mistake (two categories with the same (0,0) 
range) can we fix it?

So far you have some style generation code; and it probably would die on 
the case you describe anyways... if I cared to have specific 
functionality I would have provided test cases. Lets rock and roll...
