13  * A subclass of {@link SecurityManager} used by RMI applications that use
14  * downloaded code. RMI's class loader will not download any classes from
15  * remote locations if no security manager has been set.
16  * <code>RMISecurityManager</code> does not apply to applets, which run
17  * under the protection of their browser's security manager.
18  *
19  * <code>RMISecurityManager</code> implements a policy that
20  * is no different than the policy implemented by {@link SecurityManager}.
21  * Therefore an RMI application should use the <code>SecurityManager</code>
22  * class or another application-specific <code>SecurityManager</code>
23  * implementation instead of this class.
24  *
25  * <p>To use a <code>SecurityManager</code> in your application, add
26  * the following statement to your code (it needs to be executed before RMI
27  * can download code from remote hosts, so it most likely needs to appear
28  * in the <code>main</code> method of your application):
29  *
30  * <pre>
31  * System.setSecurityManager(new SecurityManager());
32  * </pre>
