For Solr 8.x I would stick with Java 11. 8.x has Java 8 as a minimum requirement, so I wouldn't go too far up in major versions. Also there is a known bug in Java 17 that I think would probably affect Solr 8.x, and 8.x doesn't have a workaround for it. I don't think I would trust Java 17 with anything older that Solr 9.1.1. 9.1.0 might be OK, but since there is a new patch release I'd prefer that. The same ZGC settings I gave earlier do work with Java 11. Thanks, Shawn
