The SystemThread class of the com.ms.lang package represents a thread that is always created in the system thread group (the highest level thread group, which has no parent). Untrusted code cannot create threads in the system thread group.
public class SystemThread extends Thread { // Constructors public SystemThread(); public SystemThread(String name); public SystemThread(Runnable target); public SystemThread(Runnable target,String name); // Methods public static ThreadGroup getSystemThreadGroup(); }
