There aren't much plans at all. Adding module-info.java is likely to happen in the next release, whenever that will be. Apache Commons Compress 1.20 requires Java 7. It depends on XZ for Java. I think it wouldn't be good to make XZ for Java require a newer Java version than Commons Compress but it could be discussed with Commons Compress developers. There's a bug with .7z files that requires changing both XZ for Java and Commons Compress so I could ask about the Java version too. > For example, Arrays.mismatch[1] leverages vectorized comparisons of 2 > byte[].

Thanks! These sound interesting. If they make big enough difference, it could be a good reason to require Java 9. I will need to check out the LZDecoder improvement from the other message too, and perhaps a few variations of it. Thanks! There are multiple things in XZ Utils that I try to look at in the near future so it will be a while until I will play with the Java code. -- Lasse Collin | IRC: Larhzu @ IRCnet & Freenode
