AsynchronousSocketChannel operation cancelling on b145

[Gian Franco Zabarino]

I've been testing this on b145, and after I cancel a read request by 
 cancelling the Future, I can no longer use the 
AsynchronousSocketChannel  for reading. On NIO I always had the 
opportunity to remove the key from  the Selector, and then to register 
the  SocketChannel with another selector... Is there anyway to do this 
using  NIO.2? Sometimes I need to read for detecting if a Socket was  
disconnected, and sometimes I need to read for user input. Both reads  
have different CompletionHandler classes, and different timeout  
parameters. Greetings
