[GraphHopper] Problems routing long distance routes without ch shortcuts

[Robert Schmid]

Hi,
i have experienced some problems when routing long distances without 
contraction hierarchies. If i route from south-west Bavaria to 
north-east Bavaria Graphhopper will stop throwing a java.langOutOfMemory 
exception, even my android device has 2GB of ram.
Same error occurs when i route multiple times. After routing 5-6 times 
with shorter paths the device runs out of memory, too. I need to route 
without ch shortcuts.

Thanks in advance,

Robert
