| /* @test |
| * @bug 6269166 |
| * @summary After a remote object has been exported on an anonymous |
| * port, it should be possible to export another remote object on an |
| * explicit port (and with the same socket factories, if any) with the |
| * same value as the actual port to which the first export got bound. |
| * While the fact that this works (instead of failing with a |
| * BindException) might seem odd and not to be expected, it has |
| * historically worked with the J2SE RMI implementation, so it should |
| * continue to work because existing applications might depend on it. |
