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