[GraphHopper] How to load *-gh folder? "it wasn't create via com.graphhopper.storage.GraphStorage" exception

[Peter K]

Hi Kazuki,

ah it is probably the same documentation problem Phil had (I updated the
docs now). Add this statement

hopper.setCHShortcuts(true, true)

before loading. Is it working then?

Regards,
Peter.
