>
> Minor improvements can be done on _AccessControlList_.
> Code Reusability:
> _AccessControlList_ sanitizes the input list to remove duplicate entries,
> trim entries. _StringUtils.getTrimmedStringCollection_ can be used in this
> case.
> Performance:
> _AccessControlList_ uses TreeSet to maintain set of users and groups.
> HashSet improves the performance slightly.
