/**
* 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>
