What version of opensearch-java client is compatible with OpenSearch 2.8 cluster?

Accoding to [https://github.com/opensearch-project/opensearch-java/blob/main/COMPATIBILITY.md](https://github.com/opensearch-project/opensearch-java/blob/main/COMPATIBILITY.md) opensearch-java client 2.6 is compatible with OpenSearch cluster 1.3.9-2.7.0

opensearch-java 2.6 is compatible with OpenSearch 2.8+. I’ll raise an issue in the java repo to get this fixed.
