threadpool - Java application with httpServer hangs for 45 seconds before exiting -

I'm playing with a little bit with Java Accord Class. When I run my trial application, it will primarily reach the last line (a println) in a way, but then it sits for approximately 45 seconds before closing the application. Why does it do this and there is a way to do this so that it ends up fast? Thanks

 I found something that seems to work though I'm not sure F it is the right way of dealing with this. It has not been tested extensively, but it switches it fast  
 I changed:  
  server.setExecutor (Examiner.NewCachad ThreadPaul) ); With   
:  
  Executor service excu = Executor. Newcastle Threadpool (); Server.setExecutor (excu);   
 then  server.stop (0); Before  excu.shutdown ();
