TcpWorkerThread and ThreadPool in Tomcat JK

[X f <li...@yahoo.com>]

Hi, All:
  I am confused on the codes in TcpWorkerThread and 
  ThreadPool classes in Tomcat.

  These classes are for JK connector.

  See following codes from Tomcat 4.1.8 release
-------------------------------------------------
while(endpoint.isRunning()) {
   Socket s = null;
   try {
       s = endpoint.acceptSocket();
   } catch (Throwable t) {
       endpoint.log("Exception in acceptSocket", t);
   }
    if(null != s) {
    // Continue accepting on another thread...
	endpoint.tp.runIt(this);
        try {
 	    if(endpoint.getServerSocketFactory()!
               =null) {

-------------------------------------------------

   acceptSocket would be blocked untill a socket 
   connecting to the server. If s is not null, it
   will call ThreadPool to run this TcpWorkThread.

   ThreadPool will call ControlRunnable to execute
   the above codes again. 

   So when does this recursive calling quit?


   Another question is about the ThreadPool. It uses
   an array to manage a number of ControlRunnable. In
   returnController function
----------------------------------------------------- 
   protected synchronized void returnController
               (ControlRunnable c) {
       if(0 == currentThreadCount || stopThePool) {
            c.terminate();
            return;
        }
        currentThreadsBusy--;
pool[currentThreadCount - currentThreadsBusy -1] = c;
        notify();
    }
-----------------------------------------------------

    Would this overwrite the ControllRunable object in
    position currentThreadCount-currentThreadsBusy-1?

    Is there any information to explain this 
    ThreadPool and TcpWorkerThread?

    Thanks a lot.

Cheers
