Does Java Serialization work for cyclic references?

Question

For example: Object A contains Object B that contains Object C that contains Object A.

Will Object A serialize properly?

Comment #9 here indicates that it d

Answer 1

Yes it does.

I did this very, very, simple test, and at least it finish the serialization. I assume it is correct, but you can check that with some extra lines.

import java.io.*;
class A implements Serializable { B b; }
class B implements Serializable { C c; }
class C implements Serializable { A a; }
class Test {
    public static void main( String [] args ) throws IOException {
        A a = new A();
        a.b = new B();
        a.b.c = new C();
        a.b.c.a = a;
        new ObjectOutputStream( new ByteArrayOutputStream( ) ).writeObject( a );
        System.out.println("It works");

    }    
}
