[GraphHopper] Problems with sub area

[Andreas Fischer]

Hi Peter,

I downloaded the bayern.osm from geofabrik.de and created the graph with
the graphhopper framework as usual.
I cannot test, if isFound() returns true... but i will at thursday. Some of
the valid nodes near the end of the map cannot be reached by the routing
algorithm (using CH)

Regards,
Andreas
