we compile with Java 1.7 but you can (and probably should) use the 1.8 JRE<br>
to run it.<br>
@Steve: Do you have an idea when we should move the build to 1.8 ?<br>

This happens when you try to run with Java 6 or lower. I realise that he says he on the latest version of Java and the previous version of osm combiner was running OK, so there may be more to it. The last version of mkgmap that worked with Java 6 was a long time ago.<br>
