Hi MIchael,
nope, nothing works, still the same error:
Exception in thread "main" java.lang.NoSuchMethodError:

on 2.6-SNAPSHOT.
even if I try with null:
public static FeatureCollection<SimpleFeatureType, SimpleFeature>
vectorizeRaster(GridCoverage2D viewshed){
int band = 0;
Set<Double> outsideValues = Collections.singleton(-1.0D);
Envelope2D env = null;//viewshed.getEnvelope2D();
ProgressListener progress = null;
FeatureCollection<SimpleFeatureType, SimpleFeature> fc=null;
try {
fc = RasterToVectorProcess.process(viewshed, band,
env,outsideValues, progress);
} catch (ProcessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return fc;
}
