>Description:
When serializing, and then deserializing a Vector, a  NullPointerException is thrown.  The following is a fairly short example:

import java.io.*;
import java.util.*;

public class ST {
        public static final void main(String[] args) {
                Vector v=new Vector();
                FileOutputStream output;
                ObjectOutputStream oos;

                try {
                output=new FileOutputStream("testfile");
                oos=new ObjectOutputStream(output);
                oos.writeObject(v);
                oos.close();
                } catch (IOException e) {}

                FileInputStream input;
                ObjectInputStream ois;

                try {
                        input=new FileInputStream("testfile");
                        ois=new ObjectInputStream(input);
                        v=(Vector)ois.readObject();
                        ois.close();
                } catch (IOException e) {}
                  catch (ClassNotFoundException e) {}
        }
}
