Make sense? > In the specific case of Java 8 (LTS by AdoptOpenJDK) -> Java 11 (LTS by AdoptOpenJDK), I suspect that there will be a hard requirement for most Java developers to have support for both simultaneously on their development machines because of the whole "module" thing; see below. Of course that support would ideally come via the distribution and there's a similar precedent for e.g. the node.js LTS releases, I imagine for similar reasons to do with large incompatible changes. Anyway, if such support is not offered, I'm pretty I certainly will be forced off Arch Linux for practical reasons. Btw, even though the Java language and the byte code are very stable "formats", there Java 8 -> Java 9 module transition has been everything but trivial and has required a lot of tooling/build changes which would be really hard to do across all of the ecosystem at once and any similar change in the future could hold up a a Java N -> Java N+1 migration for a pretty long time since everybody moves at their own pace. (One *hopes* that the trend will become that only the LTS-labeled versions will be used for actually releasing stuff to the world, but that the intermediate versions will be more seen as experimental. That would mean that Arch would only have to care about LTS releases.) Regards,
