I was using openjdk 7:
$ java -version
java version "1.7.0_51"
OpenJDK Runtime Environment (IcedTea 2.4.5) (7u51-2.4.5-2)
OpenJDK 64-Bit Server VM (build 24.51-b03, mixed mode)

It doesn't work with openjdk6:
$ /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java -jar -Xmx2048M /usr/share/mkgmap/mkgmap.jar --latin1 --family-id=900 --show-profiles=1 --route --add-pois-to-areas --index --product-id=1 --description= --series-name= --family-name= --gmapsupp --tdbfile rennes.osm

Could not find the main class: uk.me.parabola.mkgmap.main.Main. Program will exit.

FWIW, i've pushed the rennes.osm file i'm using to http://blop.info/pub/rennes.osm
