how to not get Error Span when calling AmazonS3Client.doesObjectExist when object doesn't exist

[randallt]

We are hitting an undesired issue where we get error spans every time AmazonS3Client.doesObjectExist is called on an object that doesn't exist. The SDK just catches the 404 exception and returns false:

    @Override
    public boolean doesObjectExist(String bucketName, String objectName)
            throws AmazonServiceException, SdkClientException {
        try {
            ValidationUtils.assertStringNotEmpty(bucketName, "bucketName");
            ValidationUtils.assertStringNotEmpty(objectName, "objectName");
            getObjectMetadata(bucketName, objectName);
            return true;
        } catch (AmazonS3Exception e) {
            if (e.getStatusCode() == 404) {
                return false;
            }
            throw e;
        }
    }

but the OpenTracing instrumentation reports that as an error deeper in the client. Is there any way we can avoid creating this error span for this normal operation?
