Exception in GraphHopperGtfs.createOrLoad() when passing an osm file


#1

Hi,

When I use GraphHopperGtfs.createOrLoad() with createWalkNetwork set to true and passing an osm file I get the following exception:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: -1

Apparently this happens while linking the stops to the underlying road network. I am pretty sure that my osm file covers the area of the GTFS data and the preprocessing of the osm file works fine. Any ideas on how I can track this down?

The last lines of the log file:

Yeah, this option is there to create a (dummy) street network rather than importing one. It’s not meant for anything serious (rather for debugging), and shouldn’t be combined with an actual road network.

I should probably remove it or prevent it from being combined with a real road network.
