Some java/security classes apply the below coding style,
Set<T> set = ...;
Set<T> unmodifiableSet = Collections.unmodifiableSet(new HashSet<>(set));
It may be unnecessary to wrap that set with HashSet before creating unmodifiableSet.
Some usages on Collections.unmodifiableList and Collections.unmodifiableMap have the same issue.
