I prefer to keep it unless it really bothers you.

it always can be null, not checking it can cause to NPE (for example: deleted
before we get to execute the command, REST request sent 10 hours after the GET
was issued..etc). therefore there's is also CDA check for that.
Line 554: vmsDiskSnapshotPluggedTo = new LinkedList<>();
Line 555: vmsDiskPluggedTo = new LinkedList<>();
Line 556: vmsDiskOrSnapshotPluggedTo = new LinkedList<>();

that was mentioned in the previous patchset, quoting the reply:
"this method populates 4 lists, what do you suggest for getter to return? the
only option i see is a map and then an enum to get the needed list by the
caller would be required..the solution i prefer is an init method for commands
that'll run after ctor. i'll push a follow up patch to add that method, as we
have dao calls in the ctor of many commands - i think that for this patch it's
good enough, let me know what's your take on that."
Line 560: for (Pair<VM, VmDevice> pair : attachedVmsInfo) {
Line 561: VM vm = pair.getFirst();
Line 562: vmsDiskOrSnapshotAttachedTo.add(vm);
Line 563: if (pair.getSecond().getIsPlugged() == Boolean.TRUE) {
