Hi,
EPSG:3879 is a CRS that is supposedly in North/East order, and GeoTools
will respect that order
unless you took explicit actions to force a east/north interpretation.
So are you giving the input point in that order?
It's difficult to give more advice just looking at a code snippet, if the
above does not solve the issue
please share a fully self contained main method that we can run locally,
along with the version of
GeoTools that you're using.
Cheers
Andrea
