GeodeticCalculator return ArithmeticException for valid points
--------------------------------------------------------------

                 Key: GEOT-1535
                 URL: http://jira.codehaus.org/browse/GEOT-1535
             Project: GeoTools
          Issue Type: Bug
          Components: core referencing
    Affects Versions: 2.0.0
         Environment: Windows 2000/ XP , Java 1.5.0.12, 
            Reporter: kevin hartwig
            Assignee: Martin Desruisseaux


We are using the GeodeticCalculator class to find the Azimuth between two 
points on the globe. When we pass the getAzimuth function 2 valid lat long 
points it is returning a ArithmeticException. This appears to be occuring 
because after 8 iterations trying to find the correct azimuth the getAzimuth 
function is to return an ArithmeticException. I have listed some points below 
which we have shown to return this exception. At this point we have no 
workaround for finding the azimuth if  one is known that would be a great help.

Anchor Point Latitude: 40.0
Anchor Point Longitude: 10.0
Destination Point Latitude: -30.0
Destination Point Longitude: -175.0

Anchor Point Latitude: 40.0
Anchor Point Longitude: 180.0
Destination Point Latitude: -30.0
Destination Point Longitude: -5.0
