new TreeSet<>() which rely on natural order,

+Reports construction of sorted collections, for example new TreeSet<>(), that rely on natural ordering,
+but their element type doesn't implement the Comparable interface.
+It's unlikely that such a collection will work properly.
- A false-positive is possible if collection element is a super-type which is not comparable, but it's intended to - hold only comparable sub-types. This is however error-prone. It's better to narrow the collection element type - or declare the super-type as comparable. -

- An option is provided to suppress the warnings on type parameters.

+ It's better to narrow the collection element type or declare the super-type as Comparable.
+ The inspection also reports cases when the collection element is a type parameter which is not declared as extends Comparable.
+ You can suppress the warnings on type parameters using the provided option (for example, to keep the API compatibility).
