Actually you can use the following (cribbed from the ImageTutorial
<http://docs.geotools.org/latest/userguide/tutorial/raster/image.html>) as
the issue is with the GeoTiff reader, which is why your JPG works.
AbstractGridFormat format = GridFormatFinder.findFormat( rasterFile );
//this is a bit hacky but does make more geotiffs work
Hints hints = new Hints();
if (format instanceof GeoTiffFormat) {
hints = new Hints(Hints.FORCE_LONGITUDE_FIRST_AXIS_ORDER,
Boolean.TRUE);
}
reader = format.getReader(rasterFile, hints);
