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