Error injecting constructor: Encoder doesn't match Sender: JSON THRIFT

Thanks for putting up this great example!

I get this error when running the application (on Fedora 26):

Oops, cannot start the server.
com.google.inject.CreationException: Unable to create injector, see the following errors:

Any idea what could be the cause?
