Thanks for picking this up one. Yes, there is an issue @return inherited 
from the methods in the interfaces but we have a tricker issue that the 
return value is ambiguous when a connected DatagramChannel is configured 
non-blocking and a zero-length datagram is received. So I suspect we 
will require additional javadoc, still thinking about this (long 
standing) issue.
