Review comment:
Of course, they are. However, here and in a lot of places in ACS, there is
an indiscriminate use of the final keyword. It does not harm, but it is
something I have to read when reviewing/coding, which does not aggregate/help.
So, I remove when they are not needed.

> Duplicated file SRs being created in XenServer pools
> ----------------------------------------------------
>
> Key: CLOUDSTACK-10241
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-10241
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Reporter: Rafael Weingärtner
> Assignee: Rafael Weingärtner
> Priority: Major
>
> Due to a race condition between multiple management servers, in some rare
> cases, CloudStack is creating multiple file SRs to the same secondary folder.
> This causes a problem when introducing the SR to the XenServer pools, as
> “there will be VDIs with duplicated UUIDs“. The VDIs are the same, but they
> are seen in different SRs, and therefore cause an error.
