> Project: Harmony
> Issue Type: Bug
> Components: Classlib
> Reporter: Vladimir Ivanov
> Assigned To: Paulex Yang
> Attachments: BufferedReaderTest.patch, CharArrayReader.patch

> 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) {
> e.printStackTrace();
> }
> }
> }
