Is LinestringM a valid geometry type in Geotools 21-RC or is my code missing
something?
I can create a LinestringM object from an array of CoordinateXYM objects. But
calling a function on the geom (e.g. line.getLength()) causes the following
error. (I’m using Java 11).
Exception in thread "MyAppClient-StreamThread-1"
java.lang.IllegalArgumentException: Invalid ordinate index: 3

Here’s my code:
CoordinateXYM[] coords = new
CoordinateXYM[num_points];
int i = 0;
for (Waypoint waypoint : waypoints) {
CoordinateXYM coord = new
CoordinateXYM(waypoint.getLon(), waypoint.getLat(), waypoint.getUnixTime());
coords[i] = coord;
i++;
}
LineString line =
geometryFactory.createLineString(coords);
System.out.println(line.getLength());
