It looks like the commons-compress library changes how it handles the file prefix. The old libraries didn't use a prefix so I had hacks in a class called CompressionActivator like the following to make it compatible with command line bzip2.
// Command line BZip2 adds "BZ" to the start of the file which // we must strip out. if (sourceStream.read() != 'B' || sourceStream.read() != 'Z') { throw new OsmosisRuntimeException( "The source stream must start with the characters BZ if it is to be read as a BZip2 stream." ); } These should be able to be removed now but I'll do some tests to make sure.
