In spite of the disadvantages mentioned above, there are certainly the cases where it is more convenient to call {@link #await()}. In such a case, please make sure you do not call {@link #await()} in an I/O thread. Otherwise,{@link IllegalStateException} will be raised to prevent a dead lock. @author The Netty Project (netty-dev@lists.jboss.org) @author Trustin Lee (tlee@redhat.com) @version $Rev: 1262 $, $Date: 2009-04-28 22:35:55 +0900 (Tue, 28 Apr 2009) $ @apiviz.owns org.jboss.netty.channel.group.ChannelGroupFutureListener - - notifies
