Open JDK's erratic behavior
Linux distros ship with Open Java and Open JDK. Cassandra does not officially support
any variant of the JVM other than Oracle/Sun Java 1.7. Open Java may cause some weird
issues, such as the GC pausing for a very long time and performance degradation. The
safest thing to do is to remove Open Java and install the suggested version.
