[classlib][io] java.io.BufferedReader.read() throws unspesified ArrayIndexOutOfBoundsException

         Key: HARMONY-841
         URL: http://issues.apache.org/jira/browse/HARMONY-841
     Project: Harmony
        Type: Bug

  Components: Classlib  
    Reporter: Vladimir Ivanov

According to specification java.io. BufferedReader.read() returns "the character read, or
-1 if the end of the stream has been reached".
The test listed below shows that RI returns -1 while Harmony throws unexpected ArrayIndexOutOfBoundsException.

=============== test.java =========================
import java.io.*;

public class test  { 
    public static void main (String[] args) {   
       try {
           System.out.println("res = " + new BufferedReader(new CharArrayReader(new char[5],
1, 0), 2).read());
       } catch (Exception e) {
