> Key: HARMONY-1103
> URL: http://issues.apache.org/jira/browse/HARMONY-1103

> The harmony method java.io.DataInputStream(null).readFully(byte[], int, int) initially
checks boundary values while RI checks stream.
> It leads to different exceptions: NPE for RI and IndexOutOfBoundsException for Harmony.
> ================= test.java =======================
> import java.io.DataInputStream;
> public class test {
> public static void main(String args[]) throws Exception {
> new DataInputStream(null).readFully(new byte[] {2, 2, 2, 2}, 1, 18);
> }
> }
> ===============================================
