Hi,
I'm trying to read in features from a shapefile and add them to a spatial
index for later processing. It has been working OK but when trying to read a
relatively large file (OpenStreetMap roads in England) I get this error:
Exception in thread "main" java.lang.IllegalArgumentException: Exponent out
of bounds

...
As I said, it works with other files (e.g. OSM for Scotland) so I'm guessing
that it's something to do with the number of features, but I can't work out
what DoubleBits is trying to do. Any ideas?
Thanks,
Nick
