@danielvsimoes the return type declared for ``NetUtils.getAllIpsFromCidr``
is ``Set`` not ``TreeSet``. This implicit assumption would break badly if the
internal implementation of the utility method were to change. Therefore,
please add a check at line 359 such as following:
```
if (allIPsInCidr == null or (allIPsInCidr != null and !(allIPsInCidr
instanceof TreeSet))) {
throw new InvalidStateException("The IPs in CIDR for subnet " + subnet +
" where null or returned in a non-ordered set.");
}
```
