Sorry, you seem to miss the point here (or maybe it's me?)

You stated that you don't think that double nor String are good choices 
for version numbers.

There's no logical reason to believe that, IMO.

Strings are as good as double for version numbers, as long as you know 
the semantics of your values and hence you know how to process them.

Your StringVersion and DoubleVersion classes, for example, could 
implement Comparator<T> and its compare() and equals() methods.

I don't see why that would be a problem.

The only reason I would not use a double for a version number is 
because, on a general principle, I don't like using inherently imprecise 
data structures to represent precise information.
