All Implemented Interfaces:

java.lang.Runnable

public class AgentThread

extends java.lang.Thread

AgentThread is the initial thread created to execute an incoming agent When an agent arrives, a new thread group is created for it, with an identifier that is unique on that server. A single thread is created in this group, and is assigned the task of executing the method specified by the agent as part of its migration request. It loads the StartUp class explicitly using our classloader and create an instance of StartUP class. Invoke the "start" method of this instance which will continue the process of deserializing the agent and invoking its action.
