/* @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.
