@UdayBidikar I did a test like "... ListBucketsResult result = client.listBuckets() ...", and was not able to reproduce your issue on 4.0.0-rc.1, facing ECS 3.8.0.5. However, the issue comes from Jackson, the ListBucketsResult and also Bucket class are using javax.xml.bind. That would be helpful if you can share more information, like your ECS version, Java version, code snippet.

@dunedodo
my test code : ListBucketsResult rslt = s3client.listBuckets()

@UdayBidikar ECS Java SDK doesn't support Java 14 AFAIK. I think it would cause the problem here. Could you try Java 8 or 11 instead? Or wait for more Java versions support, but it's of very low priority in our roadmap with no determined ETA.
