Meanwhile after some further investigation I got things to work with an older version of the JavaClient. When I am using the 7.17.18 artifacts for all the org.elasticsearch and org.elasticsearch.client artifacts and the 8.11.4 version for the co.elastic.clients elasticsearch-java artifact I can connect without problems. If I use version 8.12.1 I get java.lang.NoSuchMethodError: 'org.elasticsearch.client.RequestOptions$Builder org.elasticsearch.client.RequestOptions$Builder.setHttpAsyncResponseConsumerFactory(org.elasticsearch.client.HttpAsyncResponseConsumerFactory)'

Should I file a bug or am i doing something wrong?
