This is a feature request to move to Java 11 as a baseline instead of Java 8 (2014), and support java.util.concurrent.Flow APIs.

java.util.concurrent.Flow was introduced in Java 9 (2017) as a modern Reactive Streams API, but this project still uses the legacy org.reactivestreams APIs.

Note that while the org.reactivestreams APIs are still compiled for Java 6 (2006), a new major release of graphql-java could easily support both org.reactivestreams and java.util.concurrent.Flow APIs in a transition period.

Thank you
