@arshadmohammad My two last questions (really!):
* Is this change supposed to be applied to branch-3.4 and branch-3.5?
* I see that `DataNode.getChildren()` is called in half a dozen places with
more or less the logic below:
```
Set<String> childs = node.getChildren();
if (childs != null) {
children = childs.toArray(new String[childs.size()]);
}
// children size is zero
if (children != null) {
for (String child : children) {
// DO LOGIC
}
}
```
As `children` is zero length the for-each loop is not executed. I am fine
with leaving this code as-is. Otherwise, we could remove the now useless `if
(children != null)` calls. Wdyt?
