Durable subscription duplicated when redeploying an inboud endpoint.

Similar exception to issue wso2/product-ei#4415
...but with DURABLE subscriptions instead of NON Durable as in the other reported issue.

Should this code change be enough to fix our problem since we use Andes Release 3,2,82 and not the latest release ?

This is the call stack that we are getting:

Do you think that the patch should fix that issue too ?

Which other changes made to Andes since September 17 2018 would be required for your fix to work with our setup ?

If we upgrade Andes to the latest release, will il require upgrading the whole WSO2 too ? We currently use WSO2 6.4

Thanks
