No, there is a hard "false" for selected at creating the check box and
no modification in the source.

Do not wonder that it do not work with a bundled VM, do wonder that it  
for the uninstaller.jar self :-) On Windows used (locked) files cannot be  
deleted; to
delete uninstaller.jar we have made some hard coding around this problem.

On Windows "normaly" an uninstaller - which should deinstall a locked file  
sets a command into a special key of the registry and forces a reboot.
If you will do it, you can do it since IzPack 3.8 which offers registry  
There are more than one key for this; the names ends with "RunOnce".

But you know at this point: No warrenty in any kind...
