Description

J2SE API specifications for java.io.BufferedOutputStream.write(byte[], int, int) method says "Throws IOException - if an I/O error occurs."
Spec for the superclass java.io.OutputStream says that "If off is negative, or len is negative, or off+len is greater than the length of the array b, then an IndexOutOfBoundsException is thrown."

Harmony throws ArrayIndexOutOfBoundsException while RI throws NullPointerException.

============== Test9422 .java =====================
import java.io.BufferedOutputStream;

public class Test9422 {

public static void main(String[] argv) {
BufferedOutputStream localBufferedOutputStream = new BufferedOutputStream(

{ 2, 2, 2, 2, 2, 2, 2, 2, 2 }

;

try

{ localBufferedOutputStream.write(array0, 127, 1); System.out.println("Test filed!"); }

catch (IndexOutOfBoundsException e)

{ System.out.println("Test passed: expected " + e); }

catch (Exception e)

{ System.out.println("Test filed: " + e); }

try
