serialization of classes that require non-default constructors and extending these classes

Suppose, there's a 3rd party class:

    public class A {
        private int v;
        public A(int v) {
            this.v = v;
        }
        public int v() {
            return v;
        }
    }

If you want it to deserialize on client, you usually write a CustomFieldSerializer that calls the constructor in instantiate():

    public class A_CustomFieldSerializer extends CustomFieldSerializer<A> {
        public static void deserialize(SerializationStreamReader streamReader,
                A instance) throws SerializationException {
        }
        public static A instantiate(SerializationStreamReader streamReader)
                throws SerializationException {
            return new A(streamReader.readInt());
        }
        public static void serialize(SerializationStreamWriter streamWriter,
                A instance) throws SerializationException {
            streamWriter.writeInt(instance.v());
        }
        @Override
        public void deserializeInstance(SerializationStreamReader streamReader,
                A instance) throws SerializationException {
            deserialize(streamReader, instance);
        }
        @Override
        public boolean hasCustomInstantiateInstance() {
            return true;
        }
        @Override
        public A instantiateInstance(SerializationStreamReader streamReader)
                throws SerializationException {
            return instantiate(streamReader);
        }
        @Override
        public void serializeInstance(SerializationStreamWriter streamWriter,
                A instance) throws SerializationException {
            serialize(streamWriter, instance);
        }
    }

If someone tries to extends this class, deserialization corrupts the stream, because readInt() is not called:

    public class B extends A {
        public B() {
            super(0);
        }
    }
