There you get a lzma library for java with xz support. I think with that it
should be possible to implement a reader for zim files with lzma.
Emmanuel is right - we dropped zlib and bzip2 support since lzma is widely
available and it is better than zlib and bzip2. Dropping the support reduces
Unfortunately the documentation about zim format is not yet up to date.
