[GraphHopper] Shortest route failed (ferry issue?)

[Peter]

Hi Martin, Hi ZhiQiang,

this could be related to the bug ZhiQiang mentioned but this was already
fixed:
https://github.com/graphhopper/graphhopper/issues/367

This can only occur for shortest path routing:
https://github.com/graphhopper/graphhopper/issues/242

Martin, do you use master or a 0.4 branch?

Regards,
Peter
