The need for this method is explained below. 169N/A * Set properties to tweak DGC behavior so that this test will execute 169N/A * quickly: set the granted lease duration to 10 seconds, the interval 169N/A * that leases are checked to 3 seconds. 169N/A * Make idle connections time out almost instantly (0.1 seconds) so 169N/A * that the DGC implementation will have to make a new connection for 169N/A * each dirty call, thus going through the socket factory, where we 169N/A * can easily cause the operation to fail. 169N/A * The stub returned by UnicastRemoteObject.exportObject() does 169N/A * not participate in DGC, but it does allow us to invoke a method 169N/A * on the remote object through RMI. Therefore, we invoke the 169N/A * getSelf() method through RMI, which returns an equivalent stub 169N/A * that does participate in DGC. 169N/A * Set the socket factory to cause 3 connections attempts in a row 169N/A * to fail before allowing a connection to succeed, expecting the 169N/A * client-side DGC implementation to make at least four attempts. 169N/A * The unreferenced method was not invoked for some reason, 169N/A * but the dirty calls were clearly not retried well enough. 169N/A "test failed because dirty calls not retried enough, " +

169N/A * When all is said and done, try to unexport the remote object 169N/A * so that the VM has a chance to exit.
