Hi, I am unable to use the REST High Level Elasticsearch client on Quarkus with native image. The issue [has been referenced](https://github.com/oracle/graal/issues/460) into the GraalVM project. **How to reproduce:** 1. Instantiate a Quarkus project 2. Add the rest-high-level client to your project & implement an action (i.e. GET a document) 3. Compile in native image 4. Execute & see the error Versions: - GraalMV `20.0-b02` - Java `11.0.6+9` - Quarkus `1.5.2.Final` - Elasticsearch REST High Level client `7.8.0` - RESTEasy `4.5.3.Final` **Stacktraces:** ```auto
