Classes that have public setter methods must follow the related advice found in rule "FIO00OBJ06-J. Defensively copy mutable inputs and mutable internal components." Note that setter methods can (and usually should) perform input validation and sanitization before setting internal fields.
...
When a hash table contains references to mutable data such as a series of Date objects, each of those objects must also be copied by using a copy constructor or method. For further details, refer to rules "FIO00OBJ06-J. Defensively copy mutable inputs and mutable internal components" and "OBJ08OBJ04-J. Provide mutable classes with copy functionality to allow passing instances to untrusted code safely."
