Ideally, implement Serializable only when the class is not expected to evolve frequently. One way to maintain the original serialized form , and at the same time allowing allow the class to evolve is to use custom serialization with the help of serialPersistentFields. The static and transient fields allow one to specify what should not be serialized, whereas the serialPersistentFields field specifies what should be serialized. It also relieves the class from defining the serializable field within the class implementation, decoupling the current implementation from the overall logic. New fields can easily be added without breaking compatibility across releases.
