I wonder if this is a problem with a spurious wake up of the selector 
when there is nothing available on the channel. If this was the case 
then your Server code would expect that the channel was closed, when it 
is in fact still open and connected. This would explain the debugging 
output of the are seeing.

Would it be possible to check the value of the returned 
MessageInfo.bytes()?  bytes() will return -1 if end of stream.

Example:
   if (messageInfo != null)
       if (messageInfo.bytes() == -1)
           channel.close

What system are you running on? Maybe I could reproduce in house.
