[vbox-dev] JVM crashes

[Christophe Devriese]

Well that was exactly what I was doing. In order to make absolutely sure
Sessions are truly closed, I closed the VirtualBoxManager right along with
it. This was how I did it in python, it seems strange that it doesn't work
in java.

The test program that crashes the jvm is simplicity itself :

--------------[Test.java]--------------
import org.virtualbox_4_0.VirtualBoxManager;
import org.virtualbox_4_0.IVirtualBox;

public class Test {
        public static void main(String[] args) {
                VirtualBoxManager mgr =
VirtualBoxManager.createInstance("");
                IVirtualBox vbox = mgr.getVBox();

                mgr.cleanup();

                mgr = VirtualBoxManager.createInstance("");

                mgr.cleanup();
        }
}
--------------[Test.java]--------------
