        | AsynchronousCloseException | 
        
          Checked exception received by a thread when another thread closes the
 channel or the part of the channel upon which it is blocked in an I/O
 operation.

        | ClosedByInterruptException | 
        
          Checked exception received by a thread when another thread interrupts it
 while it is blocked in an I/O operation upon a channel.

       | 
    
  
    
  Checked exception thrown when an attempt is made to invoke or complete an
 I/O operation upon channel that is closed, or at least closed to that
 operation.  That this exception is thrown does not necessarily imply that
 the channel is completely closed.  A socket channel whose write half has
 been shut down, for example, may still be open for reading.
