Dear List,<br>
thanks a lot. <br>
With your help my problem is solved.<br>
The first and the last vertex of the polygon have been digitized
extremely close .<br>
I deleted one of these vertex and the Geoprocessing tool works.<br>

As attachment the other shape, which works with a lot of other
shapefiles.
<br>
I will try Benjamin Duke and SpatialJoes Tipp.

I have opened Rolf's shapefile and it is in EPSG:31468 or similar, so
coordinates are around (4000000, 5000000), but the error message shows
much smaller numbers. This might indicate that the error happens during
JTS internal computations (JTS bug?)
<br>
<br>
I have done a couple difference operations with it and it seems to
work.
<br>
<br>
The difference operation needs two layers. What is the other layer,
Rolf? The other layer has no problemas with other shapefiles?
<br>
<br>
