SqsException does not override the retryable method #6508
Description
Describe the bug
During the wide scale AWS issue on October 20th, 2025 one of our services experienced failures creating new SQS messages. We ended up not retrying these messages because the retryable() method on the SqsException object returned false. As far as I can tell, the retryable() method is falling back to the implementation in SdkException which is hard coded to false.
We traced out the exception which included this:
s.a.a.s.s.m.SqsException: Service returned HTTP status code 503 (Service: Sqs, Status Code: 503, Request ID:
As this failure was due to getting a 503 from the SQS service, I would have expected this to have been considered a retryable error.
Regression Issue
- Select this option if this issue appears to be a regression.
Expected Behavior
An SDK failure due to the AWS service returning 503 should result in the retryable() method returning true.
Current Behavior
retryable() is hard coded to always return false.
Reproduction Steps
SQSException (via inheritance) is hard coded for the retryable() method to return false.
Possible Solution
The retryable method should probably return true for at least 500 and 503 response codes.
