Hello Philipe
The first CRS:

has (northing, easting) axes. But the CRS read from the shapefile:

does not declare any axis order. In such case, the WKT specification mandates
that the default order is (easting, northing).
Did you tried to create the first CRS in Geotk as below?
CoordinateReferenceSystem crs = CRS.decode("EPSG:31258", true);
It should work (the 'true' boolean argument means "force (x,y) axis order"). If
it doesn't work, then I would need to look at the issue more closely.
Regards,
Martin
