I believe the following invalid ObjectStreamField definition should
result in the program failing with a WriteAbortedException or similar
exception rather than crashing with a NullPointerException.

import java.io.*;

class X implements Serializable
{
    private static final ObjectStreamField[] serialPersistentFields = {
        new ObjectStreamField("int", int.class),
    };
    private int i = 1;

    public String toString()
    {
        return "{i="+i+"}";
    }

    public static void main(String[] args) throws Exception
    {
        X x = new X();
        FileOutputStream fos = new FileOutputStream("x.ser");
        ObjectOutputStream oos = new ObjectOutputStream(fos);
        oos.writeObject(x);
        oos.close();
        System.out.println("Wrote: "+x);
        System.exit(0);
    }
}
