/* @test

 * @bug 4465315

 * @summary The RMI runtime's server-side DGC implementation object should

 * not be exported with the arbitrary access control context that was in

 * effect when it gets lazily created.  For example, calls to it should not

 * fail due to the "accept" SocketPermission check simply because of the

 * access control context that it was exported with.
