I can at least say that Solr 3.x works fine with Java 7. -Michael

Solr 3.x still works with Java 5. While I don't know of anything specific that would prevent it from working with Java 8, I have only personally ever used 3.x with Java 6.There has been no official testing. Java 8 did not exist when we were still making minor Solr 3.x releases, and Java 7 had been out for less than a year when Solr 3.6.0 was released. The best advice I can offer is to try it. Any problems are likely to NOT be subtle ... it'll most likely either work flawlessly or not at all. Because Solr 3.x works with Java 6, I think it is likely to work just fine with Java 8. Hopefully there will be someone who has actually tried it who can let you know for sure. If you can put Java 6 on the machine as well, and use that to run Solr, that would be safer. Thanks, Shawn
