Onderwerp: Java applet crashing with native assertion

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi,

this is a Java One special:

Three months ago I informed Sun Microsystems
about an applet alerting with a native win32 assertion
(Expression: offset < fFileSize

For information on how your program can cause an
assertion failure, see the Visual C++ documentation
on asserts...) .

If the users opts for cancel, it is crashing the browser
which started the applet.

The applet can be tried at the following URL:
http://www.illegalaccess.org/cms/?q=3Dnode/view/9

[How] does it crash on other platforms ? Please mail me
your experiences with it ...

Marc

This also crashes Firefox 0.8 with j2re 1.4.2_04 on RH9/x86 with the following:

java_vm: ../../../src/share/native/sun/awt/font/fontmanager/fontobjects/fontObject.cpp:418: const void * fileFontObject::ReadChunk(UInt32, UInt32, void * = 0): Assertion `offset < fFileSize' failed.
INTERNAL ERROR on Browser End: Pipe closed during read? State may be corrupt
System error?:: Success

Of course the whole idea is that Java apps will behave the same on all
supported platforms, right?

OS: Linux lisa 2.4.26-ce01 #1 mar giu 22 14:52:39 CEST 2004 i686 unknown
(nothing strange in the kernel, apart from binary nvidia drivers).

Mozilla 1.5:

Debian/1.5-3 (debian SID)

Java: Java(TM) Plug-in Blackdown-1.4.1-01

The browser crashes right away when clicking on "Crash it".

The browser doesn't crash and the applet continues to function.
