That's probably my fault :-) GeoJSON parsing has moved to gt-geojson-core
which along with the gt-geojson-store replaces the functionality in
gt-geojson. The plan is at some point in the future to remove gt-geoson but
currently GeoServer makes use of it (at least I think that was the problem)
and I ran out of time and energy,
With gt-geoson-core you should be able to do something like this:
GeometryFactory gf = new GeometryFactory();
SimpleFeatureType type = DataUtilities.createType("test",
"the_geom:Point:srid=4326");
SimpleFeatureBuilder builder = new SimpleFeatureBuilder(type);
builder.add(gf.createPoint(new Coordinate(1.23456789, 0.123456789)));
SimpleFeature feature = builder.buildFeature(null);
ByteArrayOutputStream out = new ByteArrayOutputStream();
GeoJSONWriter writer = new GeoJSONWriter(out);
writer.setMaxDecimals(6);
writer.write(feature);
