The Harmony method java.nio.ByteBuffer.wrap(byte[], int off, int len) does not throw IndexOutOfBoundsException
if off/len ==Integer.MAX_VALUE while RI throws correct exception.

================ test.java ======================
import java.nio.*;
public class test  { 
    public static void main (String[] args) {   
       try {         
           ByteBuffer.wrap(new byte[551], Integer.MAX_VALUE, 2);                   
       } catch (Exception e) {
           e.printStackTrace();
       }
    }
}
