public class AgentSecurityManager
extends SecurityManager

This class provides a simple implementation of a Security Manager allowing basically everything. The default behavior of the JAVA virtual machine forbids to load classes and native libraries from the network. To enable these features the default security manager must be replaced by AgentSecurityManager. When an agent needs to download new classes and native libraries through a NetClassLoader it must instantiate a security manager and replace the default one by adding the following line in its startup sequence : System.setSecurityManager(new AgentSecurityManager()) ;
