GraphQL Java client library : <p>I am looking for a java <em>client</em> library for GraphQL. 
This is to use for server-to-server communication, both in java.
No android, not javascript... just java.
Apollo is the nearest answer, and it seems like it is for Android only, not for plain-java applications.
Lots of examples about build server in java, nothing about client.
Any idea?
Thanks!</p>
