Success! I had to set maxnodes to 500K in the splitter and use 4G ram  
in the VM to make it work.

However.... the resulting gmapsupp.img makes my Legend Cx crash when  
it's turned off: it continously beeps and the only way to stop it is  
to remove the batteries. (I've experienced that before on gmapsupp.img  
files downloaded from the net, from sites I've now forgotten.)

With mkgmap svn630 I can create a gmapsupp.img file straight from  
denmark.osm that works in my GPS device, without using the splitter.

Is that your way of saying "wontfix" ? ;-) Sorry, but java is one of  
the few programming languages I have absolutely no skills in.

For now, we will pin mkgmap svn630 in Ubuntu.

Cheers,
Morten
