What is the status on OpenJDK support? What is broken about it? I only ask because we're pretty rabid about open source and don't really want to run the Oracle VM.

If you select latest OpenJDK 7, you'll be fine. There is minimal to no difference to Oracle JDK 7. Another story is OpenJDK 6. Avoid Open JDK 6, it is nothing stable, only a Java 7 alpha code before Java 7 officially appeared, tailored to pass JDK 6 compatibility test, full of bugs and erratic memory behavior which affect Elasticsearch performance.

I have always avoid OpenJDK like the plague because of its poor performance and random bugs. Back when I was using EC2, I would spin up a new instance and think "why is my application performing poorly?", then I would remember it came with OpenJDK as the default. I have not tried it since OpenJDK 6, so hopefully things have truly gotten better.
