Cannot read .bz2 files

[isheff]

Bug

Osmosis attempts to read .bz2 files as gzip, and fails

Steps to reproduce

On a debian linux machine:

wget https://ftp5.gwdg.de/pub/misc/openstreetmap/planet.openstreetmap.org/planet/planet-latest.osm.bz2

check the md5 hash against https://planet.openstreetmap.org/ to ensure it's correct.

wget https://github.com/openstreetmap/osmosis/releases/download/0.48.3/osmosis-0.48.3.tgz
tar zxvf osmosis-0.48.3.tgz
bin/osmosis --read-xml file="planet-latest.osm.bz2" compressionMethod="bzip2"    --write-xml file="copy.osm.bz2" compressionMethod="bzip2"

This produces the error:

I re-packed the data with gzip compression and now it seems to work. This would seem to confirm that the problem is in reading the bz2 compression.

As you did?
