Java apoptosis object; cascading abortion

Instantiating this object will cause cascading interrupts for all threads (including gui threads etc). It is useful for aborting a multi-threaded simulation from within a catch or something. Be aware, calling new Apoptosis() will end the current thread too, so you can never do anything with the object.

 // finds all the threads and kills them  
 public class Apoptosis   
 {  
      // finds all the threads and kills them  
      public Apoptosis()  
      {  
           ThreadGroup allThreads = Thread.currentThread().getThreadGroup();  
           ThreadGroup parentGroup;  
           while ( ( parentGroup = allThreads.getParent() ) != null )   
           {  
                allThreads = parentGroup;  
           }  
           allThreads.interrupt();  
      }  
 }
