Java compact2, compact3 java.rmi Class RMISecurityManager（JDK8）

@Deprecated
public class RMISecurityManager
extends SecurityManager

Implementation Note:

Applets typically run in a container that already has a security manager, so there is generally no need for applets to set a security manager. If you have a standalone application, you might need to set a SecurityManager in order to enable class downloading. This can be done by adding the following 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 main method of your application.)

    if (System.getSecurityManager() == null) {
        System.setSecurityManager(new SecurityManager());
    }
