/* @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.
