The codebase passive aggressively tells you to "upgrade" your JVM if you
use a non-Oracle environment.

The summary seems to be that Cassandra mostly works with OpenJDK, but that
it is not supported, common, or recommended. Community experiences
indicates that you will encounter far more issues with OpenJDK 6 than 7.
Cassandra 2.0 requires Java 7...

In summary, unless you absolutely *must* use OpenJDK, you should use the
Oracle/Sun JVM/JDK.
