Disable the Ctrl-Alt-Delete event through Java program

Question

I am creating a desktop application using the JDesktopPane. I'm almost complete, but when I press ctrl + alt + del, it leaves my application. How can I prevent that action?

As I'm not certain, I won't offer an official answer, but I don't believe it is possible. On Windows, ctrl-alt-del is a reserved key combination. It would be a security flaw to allow applications the ability to override it. — D.C., Apr 11 '10 at 07:47

Fact is Alt+Ctrl+Del never actually entering your application. Os traps Alt+Ctrl+Del before it is send to your application. So you can't trap it.

Alt+Ctrl+Del cannot be overridden. It is a security feature.

You cannot do that. The behavior of Alt+Ctrl+Del is enforced by the operating system, for good reasons: it makes sure that you can always bail-out of a faulty application.

http://www.codeproject.com/KB/winsdk/AntonioWinLock.aspx

lists several possibilities, from disabling the taskmanager to injecting keyboard hooks. But I doubt there's some built-in java functionality for that.
