It could be misleading to put a empty string into the expected set.
Could the lists be created depending on the OS?

private static final List<String> BZ2_TYPES = IS_WIN11_PLUS ?
     List.of("application/bz2", "application/x-bzip2", "application/x-bzip", "application/x-compressed") ?
     List.of("application/bz2", "application/x-bzip2", "application/x-bzip");


Does WIndows 11 have a (user) way to change the mapping?
For example, the mapping of .csv to vnd.ms-excel might not be correct if the user selected OpenOffice to handle .csv.  I don't think we have a mechanism to cope with that.
