Hi Shawn Unfortunately it is 8.1.1 :-(
The version of Sitecore we are on only supports this version... but I will press to get that upgraded... The thing that has me confused is the Solr doc (https://solr.apache.org/guide/solr/latest/deployment-guide/system-requirements.html) that refers to Solr 8.x and states "Requires Java 8 or higher" and "This version did have continuous testing with Java 9, 10, 11, 12 and the pre-release version of Java 13." My setup (3 nodes Cloud + external 3 ZK servers on Windows SSL) works just fine with Java 8 but with Java 11 gives broken pipe errors when posting new docs. This is such a basic thing to test that I wonder what "This version did have continuous testing with Java 9, 10, 11, 12 and the pre-release version of Java 13." actually refers to... Ta!

All versions of Solr 8 require Java 8. I have used 8.11.x with Java 11 and 17, but my setup is not in cloud mode and I have never enabled SSL. Solr 9 requires Java 11. At this time there is only one 9.x version available, 9.0.0. At this moment my Solr install is version 10.0.0-SNAPSHOT -- built from the main branch in git. I am running that with OpenJDK 11.0.15. When you say 8.1.1, do you actually mean 8.11.1? There is an 8.1.1 version, but it is over three years old now and upgrading is definitely recommended. The most current 8.x version of Solr is 8.11.2. I strongly recommend that you run the latest OpenJDK 11, and that all of your SolrCloud nodes are running the exact same version of Java. Interoperability over SSL could be a problem if the nodes are running different versions of Java. Thanks, Shawn
