- Correct Retryer bug that prevented it from retrying requests after the first 5 retry attempts.
- Note: If you have a custom
feign.Retryer
implementation you now must now implementpublic Retryer clone()
. It is suggested that you simply return a new instance of your Retryer class.
- Note: If you have a custom
