Java has quite possibly the best production GC of all the VMs out there.

  And yet operating distributed systems built on it is a world of pain. Elasticsearch, I am looking at you. Modern hardware resources leave the limitations of running/scaling on top JVM to be an expensive, frustrating endeavor. In addition to elasticsearch's metrics, there's like 4 JVM metrics I have to watch constantly on all my clusters to make sure the JVM and its GC is happy.
