Hi,

I have another question regarding osmconvert / osmosis PBF reading.

osmosis is not able to read pbf files that have no author information 
(removed with osmconvert africa.osm.pbf --drop-author 
-o=africa_noauthor.osm.pbf)

When reading the africa_noauthor.osm.pbf file with osmosis an 
IndexOutOfBoundsException is thrown. Is the author information mandatory 
for osmosis? Is it possible to change that?

Thanks
WanMil

Call:
osmosis --read-pbf file=africa_noauthor.osm.pbf --write-pbf 
file=africa_osmosis.osm.pbf
