Setting polygon line width doesn't seem to do anything

I am using the rimui_maps_lib-1.1.1 and trying to set the line width of a polygon greater than 1 but it doesn't seem to do anything. The line is still hair thin, even if I zoom in all the way. Here is my code:

LineStyle lineStyle = new LineStyle(Color.BLUE, 5);
PolyStyle polyStyle = new PolyStyle(
Color.BLUE,
PolyStyle.NO_FILL,
lineStyle
);
Polygon polygon = new Polygon(
Constants.SERVICE_AREA[i],
polyStyle
);
mapComponent.addPolygon(serviceArea);
