If a thread sets a shutdown hook using

Runtime.getRuntime().addShutdownHook();

calls via jna the method:

kernel32.CreateToolhelp32Snapshot (0x00000002, 0)

it crashes the VM. If I call the same method in the

WindowListener.windowClosing()

hook, the call does not crashes the VM.

Any idea why?

I can post part of the VM crash error report if it could be of any use.

edit: see the VM crash report on pastebin
