The source or target CRS probably doesn't contains a "TOWGS84[...]" info. In such case, Geotools doesn't know how to perform datum change. You can instruct Geotools to skip the datum change step, but in such case you will get a greater error (maybe 10 meters, maybe one kilometers... Its all depends of the CRS involved). To instructs Geotools to ignore datum change, pass a new Hints(Hints.LENIENT_DATUM_SHIFT, Boolean.TRUE) argument to FactoryFinder.getCoordinateOperationFactory. Alternatively, you can also use the CRS.findMathTransform(..., true) convenience method.
