>
> CSVFormat describes itself as immutable, but it is not @Immutable - the class
> fields are all mutable.
> The methods that change the fields do so by creating a clone, and returning
> the changed clone.
> So in a sense the class is immutable.
> However, the normal expectation is that @Immutable classes are @ThreadSafe.
> CSVFormat is not thread-safe, because the fields are not volatile, and the
> fields are not written & read using a common lock.
> The comment needs to be clarified or removed.
