This one, the patch applied... However, I get a NullPointerException 
after a while:

My command line looks like this:

java -Xmx1024m -jar dist/mkgmap.jar \
   --region-name=Switzerland --region-abbr=CH \
   --net --route  --gmapsupp --tdbfile \
   --family-name=OSM.org --latin1 --description=OSM.ch \
   --country-name="Switzerland" --country-abbr=CH switzerland.osm

BTW: could you also print out the OSM-IDs of erroneous motorway-links?

Thanks,
