The specification (ImageIO.write) reads:
"
  ...
 
  Throws: IllegalArgumentException - if any parameter is null

"

But the method write(RenderedImage im, String formatName, File output)
throws NullPointerException instead of IllegalArgumentException.

Please see test source and log bellow.

===================== write.java =======================

import javax.imageio.ImageIO;
import java.io.IOException;

import java.io.File;


public class write{

    public static void main(String argv[]) {
           
       try {

           ImageIO.write(null, null, (File)null);
           System.out.println("FAILED: No exception was thrown");

       } catch (IllegalArgumentException iae) {
           System.out.println("PASSED: Expected exception - " + iae.toString());

       } catch (java.lang.NullPointerException iae) {
           System.out.println("FAILED: Wrong exception - " + iae.toString());

       } catch (IOException io) {
           System.out.println("Exception during writing " + io.toString());
       }
   }
}
