You don't have to worry ;-) IzPack is Apache-licensed. Some 3rd-party
optional code (the look and feels) may be distributed under different

If you use a look and feel that is LGPL-licensed, you should
theoretically indicate that the installer (and not your software) is
using some LGPL-licensed code... In practice this is never an issue,
but if you want to be perfectly "clean" then I suggest that you link
to the LGPL license from your download page or whatever. I am not a
lawyer though, so if you are a business I suggest that you consult
your favorite lawyer.

Absolutely nothing, the Apache license is unobtrusive.
