[jira] Created: (HARMONY-1175) [classlib][io]
BufferedWriter.write() exception behavior differ from RI
[classlib][io] BufferedWriter.write() exception behavior differ from RI
-----------------------------------------------------------------------
Key: HARMONY-1175
URL: http://issues.apache.org/jira/browse/HARMONY-1175
Project: Harmony
Issue Type: Bug
Components: Classlib
Reporter: Denis Kishenko
1. Harmony implementation of BufferedWriter.write(String, int, int) throws an exception if len is negative while spec says (and RI follows it)
public void write(String s, int off, int len) throws IOExceptionWrite a portion of a String.
If the value of the len parameter is negative then no characters are written. This is contrary to the specification of this method in the superclass, which requires that an IndexOutOfBoundsException be thrown.
2. Harmony implementation of BufferedWriter.write(char[], int, int) throws ArrayIndexOutOfBoundsException while RI throws IndexOutOfBoundsException.
=========================== Test ===============================
import java.io.*;
public class bug9588 {
static void test(String name, Object buf, int offset, int count) {
try {
System.err.println(name);
ByteArrayOutputStream baos = new ByteArrayOutputStream(200);
OutputStreamWriter osw = new OutputStreamWriter(baos);
BufferedWriter bw = new BufferedWriter((Writer)osw);
if (buf instanceof String) {
bw.write((String)buf, offset, count);
} else {
bw.write((char[])buf, offset, count);
}
bw.flush();
System.err.println("Number of written chars: " +(baos.toByteArray()).length);
} catch (Exception e) {
e.printStackTrace();
}
}
public static void main (String [] args) throws Exception {
String str = "abcde";
char[] ch = new char[] {'a', 'b', 'c', 'd', 'e'};
test("1", str, 1, -1);
test("2", str, -1, 1);
test("3", str, -1, -1);
test("4", str, 7, 1);
test("5", str, 3, 4);
test("6", ch, 1, -1);
test("7", ch, -1, 1);
test("8", ch, -1, -1);
test("9", ch, 7, 1);
test("10", ch, 3, 4);
}

I think that this is not a problem since
ArrayIndexOutOfBoundsException is a subclass of
IndexOutOfBoundsException...

[jira] Commented: (HARMONY-1175) [classlib][io]

Tony, thanks
Now our results the same as RI

> 1. Harmony implementation of BufferedWriter.write(String, int, int) throws an exception if len is negative while spec says (and RI follows it)
> public void write(String s, int off, int len) throws IOExceptionWrite a portion of a String.
> If the value of the len parameter is negative then no characters are written. This is contrary to the specification of this method in the superclass, which requires that an IndexOutOfBoundsException be thrown.
> 2. Harmony implementation of BufferedWriter.write(char[], int, int) throws ArrayIndexOutOfBoundsException while RI throws IndexOutOfBoundsException.
