Geodetic Caluclator - Wrong distance for points on geodetic curve

When computing a geodetic curve the distance between the points on the curve is wrong.

The problem seems to be in the method "getGeodeticCurve(final int numberOfPoints)":
deltaDistance (distance between steps) = distance / (numberOfPoints+1)
loop: for (int i = 1; i < numberOfPoints; i++)
the last point before the destination point is not calculated or the distance between the points is to short

current curve (numberOfPoints = 3):
o--o-o-----o

correct curve (extend deltaDistance to distance / numberOfPoints):
o---o--o---o
or (add one extra point with running to loop one more time (for (int i = 1; i <= numberOfPoints; i++)):
o--o-o-o--o
