 ### Fixed
 - ApacheHttpClient5Transport requires Apache Commons Logging dependency ([#1003](https://github.com/opensearch-project/opensearch-java/pull/1003))
+- Preserve caller information in stack traces when synchronous callers use asynchronous transports ([#656](https://github.com/opensearch-project/opensearch-java/pull/656))
