Hello,

if I overwrite the err-Printstream using
System.setErr(..) the error messages are
printed to the system's window instead of
my Printstream ( for example StringOutOfBounds-
Exception in String.substring; it seems to
be native hard-coded. I'm using my own
window to make my application pure Java.

I think this is the problem being reported.

import java.io.*;

public class Test {
    public static void main(String [] args) throws Exception {
System.setErr(new PrintStream(new FileOutputStream("foo")));
System.setOut(new PrintStream(new FileOutputStream("bar")));
String s = "abc";
System.out.println(s.substring(1, 4));
    }
}

In jdk1.4-beta3-b84, winNT or win98:
$ java Test
Exception in thread "main" $ ls -s foo bar
  0 bar 1 foo
$ cat foo
java.lang.StringIndexOutOfBoundsException: String index out of range: 4
        at java.lang.String.substring(String.java:1446)
        at Test.main(Test.java:8)

The "Exception in thread ..." message does not appear on Solaris.
