NullPointerException on WrappingProjectionHandler when rewrapping all the
clones into a single geometry
-------------------------------------------------------------------------------------------------------
Key: GEOT-2988
URL: http://jira.codehaus.org/browse/GEOT-2988
Project: GeoTools
Issue Type: Bug
Components: core render
Affects Versions: 2.5.8
Reporter: Alessio Fabiani
Assignee: Andrea Aime
Priority: Critical
The postProcess method of the WrappingProjectionHandler performs a check in
order to rewrap all the clones into a single geometry.
The code below is a snippet of the algorithm:
// rewrap all the clones into a single geometry
if (Point.class.equals(geomType)) {
Point[] points = (Point[]) geoms.toArray(new Point[geoms.size()]);
return geometry.getFactory().createMultiPoint(points);
} else if (LineString.class.isAssignableFrom(geomType)) {
LineString[] lines = (LineString[]) geoms.toArray(new
LineString[geoms.size()]);
return geometry.getFactory().createMultiLineString(lines);
} else if (Polygon.class.equals(geomType)) {
Polygon[] polys = (Polygon[]) geoms.toArray(new
Polygon[geoms.size()]);
return geometry.getFactory().createMultiPolygon(polys);
} else {
return geometry.getFactory().createGeometryCollection(
(Geometry[]) geoms.toArray(new Geometry[geoms.size()]));
}
On the above code there is no check for geomType == null thus causing the
method to throw Null Pointer Exceptions in such cases.
