Converting osm to .obj gets stuck

I am trying to convert manually selected OSM to .obj
max latitude 37.45741924441423
min latitude 37.454725015309435
min longitude 127.07585562251147
max longitude 127.07740478872505

java -jar ./OSM2World.jar -i ./map.osm -o ./map.obj --performancePrint

what could be the cause of it getting stuck?
