I came across a problem trying to persist MonetaryAmount instances like FastMoney with Spring Data MongoDB in a forked project:
org.springframework.data.mapping.model.MappingInstantiationException: Failed to instantiate org.javamoney.moneta.FastMoney using constructor NO_CONSTRUCTOR with arguments

Basically FastMoney or Money do not have a constructor. It seems SpringData relies on a constructor here.
Does this work with JNoSQL? If so I could try to migrate the persistence module to it. Help is greatly appreciated if you have not problem with that code under the GPL. I'd propose a PR to the original project if it works, otherwise there are no problems, we just must refrain from using anything directly in JNoSQL examples ;-)
