Create a Postgres table with geometry(point, 3857) column, then try to persist a JTS Point into it with 3857 SRID. You will get an error saying that SRID 3875 geometry cannot be saved into a SRID 3857 column, due to this GeoLatte bug:
https://github.com/GeoLatte/geolatte-geom/issues/41

Please update to GeoLatte 1.0.3 that fixes this bug.
