'serialPersistentFields' field not declared 'private static final ObjectStreamField[]'

Reports Serializable classes whose serialPersistentFields field is not declared as private static final ObjectStreamField[].

If a serialPersistentFields field is not declared with those modifiers, the serialization behavior will be as if the field was not declared at all.

Example:

  class List implements Serializable {
    private List next;

    ObjectStreamField[] serialPersistentFields = {new ObjectStreamField("next", List.class)};

  }
