[izpack-devel] Shortcut Panel Crashes on Windows 2000

Hal,

hmmmm, interesting...

I think it would be a good idea to try to isolate this problem to the use of
a specific module. From what you write it sounds very much like the shortcut
panel is the culprit. However, there is no proof at this point. So before
spending a lot of time on digging into this area it might be valuable to
first make sure it is actually in this module.

The 20 min thing is not exactly helping... can you put a dummy together that
does not take that long to build and see if that exhibits the same problem?
if so, we can use that to debug the problem if not we would probably have to
search into an entirely different direction...

BTW, I got to go and drink some beer pretty soon, you can reach me for about
another 1/2 hour and after that tomorrow morning again (US Pacific Time).

	Elmar

Okay.  I forgot who write the DLL.  I see what you're saying.  My
misunderstanding.

What's weird is that it isn't a crash, a blue-screen-of-death, or
anything else.  It's a total reboot, and I just can't imagine a darn
thing in Java doing that.  I can try redirecting the output and errors
to a file next time, if you think that'll help.

I know it works in WinXP.  I haven't experimented too much yet, since it
takes 20 minutes to compile the Install.jar!  I'm open to ideas of what
to change.

I can try different settings.  I think it best to remove one of the
short cuts and that could narrow it down quickly.  I was worried that
the SimpleConfig.class that Fabrice and I have been working on could
cause some problem, but it's not in use at all when ShortcutPanel is
working -- and I just don't see what could be going on in Java that
could automatically reboot the system.

It could be any of those.  It's on a multi-partitioned system, and the
partition was set up for testing, so it would be a pain to reinstall
Windows, since I'd still have to go back and re-install GRUB over the
boot block and make sure the config is okay.

I'm using Java 1.5, if that helps.
