[osmosis-dev] bounding-polygon dismisses points at +180° longitude

[WanMil]

Although I wrote to Brett directly that extending the polygon to 181° 
works I have observed that is works only for osm input but not for pbf 
input.

osmosis --read-pbf file=180.osm.pbf --bounding-polygon file=asia.poly 
--write-xml file=filtered.osm
throws an exception:

So the pbf parser should be changed.
