> default.)
> Components: Management Server

> Secondary Storage garbage collector failed with NPE in case of S3 storage
> provider
> Steps to Reproduce:
> ================
> 1.Bring up CS in advanced zone with S3 as the secondary storage provider
> 2.After SSVM is up and running register ISO to CS
> 3.When the ISO is in ready state delete the iso
> 4.Wait for the Storage scavenger thread to run
> Observations:
> ============
> After deleting the ISO , it is marked as destroyed in template_store_ref
> table and also got deleted from S3 object store. But when secondary storage
> garbage collector ran it found 1 template to clean up on secondary
> storage(Image Store not on ImageCache store) since the iso state is in
> destroyed state and tried to clean it up.
> Found NPE while trying to clean up from Image store:
