When a primitive type's class is serialized, this is not
received properly upon reading (only tested this to/from file
serialization).

Steps:
serialization:
1. Class c = Integer.TYPE // get the class of the primitive
2. objectOutputStream.writeObject (c); // serizalize

deserialization:
1. Class c = (Class) objectInputStream.readObject ();
output:
java.lang.ClassNotFoundException: int
        at java.io.ObjectInputStream.readObject(ObjectInputStream.java:347)
        at java.io.ObjectInputStream.readObject(ObjectInputStream.java:232)
        at sr.firm.welch.brian.Tester.main(Tester.java:23)

Code that demonstrates this:
> Begin code example
package sr.firm.welch.brian;

import java.io.*;
import java.lang.reflect.*;

public class Tester
{
   public static void main (String args[])
   {
      try
      {
         // serialize
         FileOutputStream fos = new FileOutputStream ("intClass.ser");
         ObjectOutputStream oos = new ObjectOutputStream (fos);
         Class c = Integer.TYPE;
         oos.writeObject (c);
         oos.close ();
         fos.close ();

         // deserialize
         FileInputStream fis = new FileInputStream ("intClass.ser");
         ObjectInputStream ois = new ObjectInputStream (fis);
         c = (Class) ois.readObject (); // This is where the exception is thrown
         System.out.println ("This is never reached");
         ois.close ();
         fis.close ();
      }
      catch (Exception except)
      {
         except.printStackTrace ();
      }
   }
}
> End code example
