It's related to the JEE concurrency utilities. A complement to the SE
version that you mention. See:
https://docs.oracle.com/javaee/7/tutorial/concurrency-utilities002.htm#CIHFBCFH
They provide managed executors for runnable, etc. They were created to
address the fact that you should not start your own threads inside a container.
These utilities basically manage the threads lifecycle for you.
And yes, they use Future. I'm using CompletableFutures, which itself
implements Future because it's more powerful and less known. This way we get a
double advantage with the example.
I'll probably take some time to explain all this and provide more context
in the Readme.
