That's because the default longFileMode is LONGFILE_ERROR, which
throws an exception for filenames longer than 100 characters. Switch
to LONGFILE_POSIX. While at it, handle large files and filenames with
strange encodings, too.
This requires commons compress 1.4, which introduced support for large
files and POSIX long filenames.
