java.io.ObjectInputStream.registerValidation() doesn't throw NotActiveException when it is
invoked for a stream which is not currently reading objects. Such behavior contradicts to current
javadoc.

The javadoc says:
------------------------
registerValidation
............................

      Throws:
            NotActiveException - The stream is not currently reading objects so it is invalid to
            register a callback.
 ..................
------------------------

This sample is showing a bug:
---------------------------------
import java.io.*;

class ValidObj implements Serializable, ObjectInputValidation {

    transient boolean validated = false;

    public ValidObj() {}
 
    public void validateObject() throws InvalidObjectException {
        validated = true;
    }

    public boolean isValidated() {
        return validated;
    }
}

public class test {

  public static void main(String[] args) {
    try {
        ByteArrayOutputStream b = new ByteArrayOutputStream();
        ObjectOutputStream oos = new ObjectOutputStream(b);
        oos.writeObject(new String("test"));
        oos.close();
        ByteArrayInputStream bais = new ByteArrayInputStream(b.toByteArray());
        ObjectInputStream ois = new ObjectInputStream(bais);
        ois.registerValidation(new ValidObj(), 0);
        System.out.println("NotActiveException is not thrown");
    } catch (NotActiveException e) {
        System.out.println("OKAY");
    } catch (Exception e) {
    }
  }

}
---------------------------------

Output:
-----------------------------------
NotActiveException is not thrown
-----------------------------------

It needs to be fixed.
