Hi, Java 25 has been released, and Solr 10.0 release is in progress. I (or rather Bernd Wahlen, the JIRA reporter), have proposed to use JRE25 as base image from the get go, see https://issues.apache.org/jira/browse/SOLR-17908. There was a short discussion in that JIRA, bot not really conclusive.
The only argument I can think of for using Java 21 as base image is that it still has the Security Manager. But in a container world that has limited utility anyway. I prepared https://github.com/apache/solr/pull/3782 to make it happen, and plan to merge by lazy consensus on Monday. Jan
