Thanks for the reference, very helpful.

P.S.:

Just out of habit I would code:

   if ((key.readyOps() & SelectionKey.OP_ACCEPT)
      == SelectionKey.OP_ACCEPT) {

      // Accept the new connection
      // ...
   }

With a different check:

   if ((key.readyOps() & SelectionKey.OP_ACCEPT)
      != 0) {

      // Accept the new connection
      // ...
   }

The same check is also used in the definition
of the method isAcceptable(), so it could be
also coded as:

   if (key.isAcceptable()) {

      // Accept the new connection
      // ...
   }
