On GH 0.7, when generating graphs (./graphhopper.sh import *.osm.pbf), the log shows many warnings such as :
2016-10-21 15:55:01,467 [main] WARN com.graphhopper.reader.osm.conditional.ConditionalTagsInspector - 8104512 - could not parse the conditional value:no @ week 44-22 of tag:access:conditional. Exception:Unparseable date: “week 44”
Is it expected ? Does it come from OSM data issue?
