Channel groups are only needed if you are sharing resources so if you 
don't need this then you don't need to associate the channel with a 
group. I recall your previous mails where you were working on a channel 
to a serial port. Is this still the case? I will guess that a typical 
application won't require a huge number of channels, in which supporting 
channel groups may be overkill anyway.

IllegalChannelGroupException (an IllegalArgumentException) is probably 
best.
