JTS.orthodromicDistance fails for DefaultGeographicCRS.WGS84
------------------------------------------------------------
Key: GEOT-942
URL: http://jira.codehaus.org/browse/GEOT-942
Project: GeoTools
Issue Type: Bug
Affects Versions: 2.3.M0, 2.3
Reporter: Aleksander Bandelj
This affects UDIG, which uses the following to calculate scale:
diagonalGroundDistance = JTS.orthodromicDistance(new Coordinate(restrictedBounds
.getMinX(),
restrictedBounds.getMinY()), new Coordinate(restrictedBounds
.getMaxX(),
restrictedBounds.getMaxY()), DefaultGeographicCRS.WGS84);
For example:
JTS.orthodromicDistance(new Coordinate(1, 1), new Coordinate(2, 2),
DefaultGeographicCRS.WGS84);
gives
java.lang.IllegalArgumentException: Argument "crs" should not be null.

Reason is probably optimization in TransformedDirectPosition constructor since
2.2:
defaultCRS = CRSUtilities.equalsIgnoreMetadata(sourceCRS, targetCRS) ? null :
sourceCRS;
which leaves crs as null
