Right, I suspect David may have mis-read the discussion as it may not be 
obvious that Socket::getInputStream and Socket::getOutputStream return 
streams that implement close to close the Socket. One detail on shutdown 
is that the close may shutdown the stream for writing as part of the 
close. This is normal and long standing behavior for cases where 
SO_LINGER has not been set.
