The oh so delightfully names Thread-4 appears sitting in running state all 
the time (from typing 'threads' three times), and Thread-5 sits in 
sleeping state.

and:

Thread-4[1] where
  [1] java.net.PlainSocketImpl.socketAccept (native method)
  [2] java.net.PlainSocketImpl.accept (PlainSocketImpl.java:384)
  [3] java.net.ServerSocket.implAccept (ServerSocket.java:450)
  [4] java.net.ServerSocket.accept (ServerSocket.java:421)
  [5] org.griphyn.vdl.karajan.Monitor$Service.run (Monitor.java:428)
  [6] java.lang.Thread.run (Thread.java:613)

Thread-5[1] where
  [1] java.lang.Thread.sleep (native method)
  [2] org.griphyn.vdl.karajan.InHook.run (InHook.java:54)
  [3] java.lang.Thread.run (Thread.java:613)

Let me know what else you want...
