Bug report

[Eduard Bloch <edi at gmx dot de>]

Hello,

a Debian developer told me to report this bug to you:

----- Forwarded message from Eduard Bloch <blade@debian.org> -----

Date: Thu, 18 Oct 2001 20:46:41 +0200
From: Eduard Bloch <blade@debian.org>
Subject: gcj-3.0: FileWriter problems
To: Debian Bug Tracking System <submit@bugs.debian.org>

Package: gcj-3.0
Version: 1:3.0.2-0pre011014
Severity: normal

Hello, following simple Java program crashes when compiled with gcj. If
I compile with javac and run it in kaffe, it works flawless. When
compiled with gcj...
gcj-3.0 -g fromFileToFile.java --main=fromFileToFile
then following happens:
./a.out einsteiger.txt asdf
Error while creating the new file...

And if I change the Exception to IOExcepion (as it should be), it
crashes or exits.

./a.out einsteiger.txt asdf
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException
   at 0x4018e174: java.lang.Throwable.Throwable() (/usr/lib/libgcj.so.2)
   at 0x4018475c: java.lang.Exception.Exception() (/usr/lib/libgcj.so.2)

Gruss/Regards,
Eduard.
