I agree on being conservative here. But if it turns out to work well, we could consider publishing an additional solr:9.4.0-jre21 tag. That way early adopters have a choice. If I remember correctly, Java 21 has some improvements that can benefit some vector workloads or something, so I see a benefit in getting it out there. We could alternatively opt to push temporary images like this to our own apache/solr docker namespace for folks to try out.
