[izpack-users] Problem creating shortcuts with Windows(UnsatisfiedLinkError)

[miraodb]

Hi Benjamin,

Can you send us your shortcut specs and install.xml
This looks like something is wrong in the xmls.
I might have worked in previous versions because it wasn't as strict as now. 
Just an assumption though.

Cheers,
Fabrice
