You can use something like (from
https://docs.geotools.org/stable/userguide/library/referencing/crs.html#matching-a-coordinatereferencesystem
):
CoordinateReferenceSystem crs = CRS.decode("EPSG:32735");
Formattable f = (Formattable) CRS.decode("EPSG:32735", true);
String wkt = f.toWKT(Citations.ESRI, 2); // use 0 indent for single line
System.out.println("wkt for EPSG:32735 (ESRI)");
System.out.println(wkt);
To produce a more ESRI friendly WKT in your .prj file. I thought there was
a flag you could pass to the ShapefileWriter to set that up but I can't see
it on a quick look.
Alternatively, you could open a bug report with ESRI asking them to support
the standard better.
