V6065. A non-serializable class should not be serialized.

Dec 14 2018

The analyzer has detected serialization of an object that lacks the implementation of the 'java.io.Serializable' interface. For correct serialization and deserialization of an object, make sure its class has this interface implemented.

Consider the following example:

class Dog
{
  String breed;
  String name;
  Integer age;
  ....
}
....
Dog dog = new Dog();
....
ObjectOutputStream oos = new ObjectOutputStream(fos);
oos.writeObject(dog);
....

If it comes to serializing the 'dog' object, a 'java.io.NotSerializableException' will be thrown. To ensure correct execution of this code, the 'java.io.Serializable' interface needs to be implemented in the 'Dog' class.

Fixed code:

class Dog implements Serializable
{
  String breed;
  String name;
  Integer age;
  ....
}
....
Dog dog = new Dog();
....
ObjectOutputStream oos = new ObjectOutputStream(fos);
oos.writeObject(dog);
....
