Hi,
Actually I also did another test as following. When I comment the "new Connet", the program works well. So this is the problem related to
Libvirt JNA. If I manually run the garbage collection for this program, it still works well. But if I run the garbage collection for the last problem,
It will crash. I guess this problem is caused by ConnectAuth callback. When garbage collection is executed, the callback memory is moved.
B.R.

Then it's a java bug. The loop doesn't call or use libvirt in any way.
If it crashes in the loop it's java crashing to me !
