title: InvalidParameterException while confirming SNS notification using Java spring cloud aws
body: <p>I have SNS http end point written using Spring-aws-cloud. I followed the below <a href="http://cloud.spring.io/spring-cloud-aws/spring-cloud-aws.html#_annotation_driven_http_notification_endpoint" rel="noreferrer">tutorial</a>. While I request confirmation from my SNS topic I get the following error from my application console. Seems the status.confirmSubscription() is failing. 
  Error I am getting is : </p>
