Awesome !! Thanks for this

I believe this was discussed in chat @phillip-kruger, but I forgot about it and hit it with a new module I wrote using the graphql client. There is a requirement for the rest client extension, else the graphql client fails at runtime in native mode with Exception in thread "Lambda Thread" java.util.ServiceConfigurationError: io.smallrye.graphql.client.typesafe.api.GraphQlClientBuilder: Provider io.smallrye.graphql.client.typesafe.impl.GraphQlClientBuilderImpl not found

Yea, at this point our smallrye client just use rest client as a transport protocol. We still need to do some work there.

From end users perspective, transport really doesn’t matter so long as the transitive dependencies “just work.” In this case they did not, although I must admit that is one of the more confusing issues I’ve hit in graal native.
