[GraphHopper] The logic and comment are not the same meaning.

Hi,

I am looking at the NameIndex.
The pointer is long.

private long bytePointer = START_POINTER;

if (bytePointer < 0)        {            throw new
IllegalStateException("Way index is too large. Cannot contain more than
2GB");        }

if bytePointer < 0, it could be larger than 2^63, way more than 2GB
