+
+Investigations for issue https://github.com/quarkusio/quarkus/issues/43756[quarkusio/quarkus#43756]
+
+Same implementation as link:../superheroes-graphql-client[superheroes-graphql-client] but without quarkus.
+
+To run it:
+
+```
+./gradlew run
+```
+
+The main class is link:src/main/java/run/Client.java[Client.java]
+The client model classes and interface are the same as in the quarkus application (packages `superheroes.api` and `superheroes.model`)
+
+Use `gradle.properties` to change the smallrye version.
+
+=== With 2.9.2
+
+```
