when you run a polyglot stack with java/python/go/node on top of a cluster of machines, you will love to have them containerized and uniform. It makes scripting and CI so much easier.

or, when you have a legacy app that relies on java 6, but you want everything else to run on java 8, the ability to drop everything into a container with its runtime is a life saver.

We already run a polyglot stack at our company, and we use Docker(nvidia-docker) for our Python environment. With Java there is no need, and it is a lot less work updating and upgrading the JVM and our Java applications. I would use Docker for Java 6 though.
