Weird, could have sworn I changed that. Will be private in the next patch.

That was actually an artifact of an earlier version. You're right in that it's
not needed here. Will be removed in next patch.

I had actually written up this block of code as you have suggested but chose to
keep it this way as I thought it looked easier to follow. Investigating online
showed that this is really a matter of taste. However, I don't want to get in a
battle over this and it appears to be the consensus here to go your route, so
I'll code it that way in the next patch.

single volume associated with the

and move on to the next.

Will do as stated above.
Line 46: Guid volumeId = volumesList.get(0);

Makes sense. I'll set the exception string on the return value as well.

Yes, I normally do that. Not sure why I had it on a separate line here. Will
move up for next patch.

I've heard arguments both ways for a single line if or else clause. I tend to
go with always wrapping as if some code needs to be added later to the
statement it's less likely to cause a problem.

I've removed the check as the parameters will fail to initialize if disk image
is null anyway.

I've removed the @NonTransactiveCommandAttribute annotation as this should be
in a transaction.

I think it was an artifact of copying another test. Removed.

I've moved them to the setup.

Line 49:
Line 50: private List<Guid> importDiskIds = new
ArrayList<Guid>(Arrays.asList(importDiskId, existingDiskId));
The list is returned from a query and the command modifies it, however a list
returned by Arrays.asList() is immutable and throws an exception during the
modification. Wrapping it in a new ArrayList() allows for mutation while
keeping the initialization on a single line. I'll add a comment as it may
confuse future readers of the code.

Commit Message
Line 30: storage domain, I found that it returned a list of storage
Line 31: pools. I am assuming that an NFS based storage domain would
Line 32: only belong to a single storage pool and thus I took the first
Line 33: item in the list. If this assumption is unfounded please note
Line 34: in the review.
I've added a check in the canDoAction methods of the query and command to
verify the domain is a data domain.
