Subject RE: Lucene Version Upgrade (3->4) and Java JVM Versions(6->8)
Date Tue, 27 Jan 2015 19:49:45 GMT
Java 8 update 20 or later is also fine. At current time, always use latest update release and
you are be fine with Java 7 and Java 8. Don't use older releases and don't use G1 Garbage
Collector.
