Hello Rolf
 
Voilà !

Is this what you are trying to do?
It worked using gvSIG 1.10 without any change in your shapefiles.
which version are you using?

Hello,
and thanks a lot for your efforts.
As attachment the other shape, which works with a lot of other shapefiles. 
I will try Benjamin Duke and SpatialJoes Tipp.

	Hello,
	 
	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?)
	 
	I have done a couple difference operations with it and it seems to work.
	 
	The difference operation needs two layers. What is the other layer, Rolf? The other layer has no problemas with other shapefiles?
	 
	Regards,
