| /* @test |
| * @bug 4308492 |
| * @summary In addition to keeping the VM alive (with a non-daeman thread) |
| * while there are remote objects exported, the RMI runtime should also |
| * keep it alive while there remain calls in progress (to remote objects |
| * the have presumably been unexported), so that a remote object can more |
| * conveniently implement a graceful remote shutdown method (that unexports |
| * the object). |
