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