If you look at the open methods you will see that they are specified to 
throw ShutdownChannelGroupException if you attempt to open a channel in 
a group that is shutdown.

Also, the I/O methods where you specify a completion handler, and 
attempt to initiate an I/O operation on a channel in a group that has 
terminated. This case has to fail with the initiating thread throwing an 
exception (because the completion handler cannot be invoked).
