| * @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. |
