There are no good reasons to do Java 17 and it is way too early.
Reagrding real optimizations, Lucene 17 is unfortunately not containing Project Panama or Vector API, so it looks more like Java 18/19 is a good candidate as a new minimum at a later stage. I’d release Lucene 9 with Java 11 (which is LTS) and then decide later if we update to some post-17 version to get the new vector and panama APIs (vector search, SIMD and also MMapDirectory v2). If we do this, we should simply release Lucene 10.

Will we support both? If so, would Java 11 support likely continue for the entire 9.x release line? Is there a JIRA tracking this? Thanks, Mike
