If I remember right, you are running SolrCloud ... which means you're on at least 4.x. I have not heard about any problems running Solr in Java 8, but I only have concrete information for 4.x and later. I've heard indirectly that 3.x does work, but I haven't confirmed that rumor. I am running 4.9.1 on Java 8 for one of my indexes and it is working very well. Whether you use Java 7 or 8, you should definitely use the latest release. OpenJDK 7 and later is good, but the Oracle version is recommended. Thanks, Shawn
