|
|
* @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.
