Hi, .xz is to LZMA what .gz is to the DEFLATE compression algorithm, and it starts to get used by quite a few tools/systems in the Unix/Linux world. For example more recent GNU tar versions use -J to support the format (like -z for gzip and -j for bzip2), the GNU core utils come with an xz command and recent RPMs can use .xz compressed tarballs as well. This is a format we want to support 8-)
Lasse Collin the author of the public domain "XZ in Java" package[1] has offered to help us build Compressors on top of his package. We basically have two options: * forking the required classes of "XZ in Java" into Compress (Lasse already has a CLA on file and I'm sure we could arrange for the two code bases to stay in sync) * add a (optional) binary dependency on "XZ in Java". Currently the package is not available via a Maven repo, but this can probably be arranged as well. The first option would allow us to support the format without requiring another JAR, the second one may be less work from a maintenance POV. Shading a binary dependency could provide some middle ground. Which option do we prefer?
