 /**
  * An ObjectInputStream deserializes primitive data and objects previously
  * written using an ObjectOutputStream.
  *
+ * <p><strong>Warning: Deserialization of untrusted data is inherently dangerous
+ * and should be avoided. Untrusted data should be carefully validated according to the
+ * "Serialization and Deserialization" section of the
+ * {@extLink secure_coding_guidelines_javase Secure Coding Guidelines for Java SE}.
+ * {@extLink serialization_filter_guide Serialization Filtering} describes best
+ * practices for defensive use of serial filters.

  * <p>ObjectOutputStream and ObjectInputStream can provide an application with
  * persistent storage for graphs of objects when used with a FileOutputStream
  * and FileInputStream respectively.  ObjectInputStream is used to recover
  * those objects previously serialized. Other uses include passing objects
  * between hosts using a socket stream or for marshaling and unmarshaling
