| * The test is manual because the (non-local) host and port running JMX must be supplied as properties. |

| /** |
| * Verify that access checks for the Registry exported by JMX Registry.bind(), |
| * .rebind(), and .unbind() are prevented on remote access to the registry. |
| * The test verifies that the access check is performed *before* the object to be |
| * bound or rebound is deserialized. |
| * This tests the SingleEntryRegistry implemented by JMX. |
| * This test is a manual test and uses JMX running on a *different* host. |
| * JMX can be enabled in any Java runtime; for example: |
| * login or ssh to the different host and invoke rmiregistry with arguments below. |
| * It will not show any output. |
| * {@code $JDK_HOME/bin/rmiregistry \ |
| * -J-Dcom.sun.management.jmxremote.port=8888 \ |
| * -J-Dcom.sun.management.jmxremote.local.only=false \ |
| * -J-Dcom.sun.management.jmxremote.ssl=false \ |
| * -J-Dcom.sun.management.jmxremote.authenticate=false |
| * } |
| * On the first host modify the @run command above to replace "jmx-registry-host" |
| * with the hostname or IP address of the different host and run the test with jtreg. |
