OK. That's not a problem.
It is possible to replace current factory with new one for particular
geometry object or to create new factory customized properly and use it
to build geometries.
Shared smart pointer idiom helps to handle both cases.

Yes, but that not a problem :-)
I mean, first all assumptions have to be considered in details.
And when those assumptions are stable, then it is possible to implement
the solution properly: in Java or in C++, it does not matter, just using
tools that particular language provides.
