Okay tried out your idea Gabriel.
There are actually two factory finders in play:
- BasicFactories - used by the geometry library implementations; never hooked
up to gt-referencing (and should be used by gt-referencing when creating direct
positions)
- CommonFactoryFinder
The superclass you mentioned, FactoryFinder, is actually abstract.
I did try a couple of things:
- moving to gt-metadata; failed as the code references ReferencingFactoryFinder
(probably not that big a deal as we could just reverse the relationship)
- moving to gt-referencing; failed as CommonFactory finder references
FeatureCollection which is part of gt-api and not an gt-opengis interface
I am going to go away and think for a bit.

Gaining the trust of online customers is vital for the success of any company
that requires sensitive data to be transmitted over the Web. Learn how to
best implement a security strategy that keeps consumers' information secure
and instills the confidence they need to proceed with transactions.
