I would prefer Oracle to own an Azul's Zing JVM over any other (GC) to provide it for free for anyone :)

Oracle now owns the sun hotspot team, which is inarguably the highest powered java vm team in the world. Its still really the epicenter of all java vm development.

There have been tons of threads/convos on this. In the early days of Java 7 it was pretty unstable and there was pretty much no convincing reason to use Java 7 over Java 6. Now that Java 7 has stabilized and Java 6 is EOL it's a reasonable decision to use Java 7 and we do it in production with no issues to speak of. That being said there was one potential situation we've seen as a community where bootstrapping new node was using 3x more CPU and getting significantly less throughput. However, reproducing this consistently never happened AFAIK. I think until more people use Java 7 in production and prove it doesn't cause any additional bugs/performance issues Datastax will update their docs. Until now I'd say it's a safe bet to use Java 7 with Vanilla C* 1.2.1. I hope this helps!

The Datastax docs repeatedly say (e.g. http://www.datastax.com/docs/1.2/install/install_jre) that Java 7 is not recommended, but they don't say why. It would be helpful to know this. Does anyone know? The same documentation is referenced from the Cassandra wiki, for example, http://wiki.apache.org/cassandra/GettingStarted - Baron
