The sayHello demo fails

It's because the config.json uses a store named quick_start_demo:

but the demo uses helloworld:

What you expected to happen:

How to reproduce it (as minimally and precisely as possible):
Follow the readme https://github.com/layotto/java-sdk#2-run-the-examples and then run the Hello.java demo
