Note that defensive copies performed during execution of a constructor must avoid use of the clone() method when the class could be subclassed by untrusted code. This restriction prevents execution of a maliciously crafted overriding of the clone() method. For more details, see rule OBJ07-J. Limit extensibility of classes and methods with invariants to trusted subclasses onlySensitive classes must not let themselves be copied.
Classes that have public setter methods, that is, methods whose purpose is to change class fields, must follow the related advice found in rule OBJ06-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.
