Ok, I wrote this mail a little too fast. I saw dedicated page on axis order and it solved my problem. (http://docs.geotools.org/latest/userguide/library/referencing/order.html)
But if I can make an observation, as a beginner I think it is a little bit strange to set a particular CRS and retrieve another.
