Okay, I reordered.

Okay, I did not think of that -- 
With reordered and valid xml I get the same errors:
(this time at panel activation because of the update, see below)

could not create shortcut instance

I have only two windows boxes at my workplace, and both show the same
Exception. One is a Windows 2003 Terminalserver, the other a notebook
with XP Professional (I think). I will try to boot my XP Professional
at home this evening. (didn't do that for ages ;)

I just updated from svn and now the behaviour is as you expected,
the exceptions are coming at panel activation.

I'll try to get a JDK installed on the terminal server and test building
the installer there next...
