Hello,

There are two ways to wait for the completion of the I/O request.  The
first approach is to call await() or awaitUninterruptibly() of the
ChannelFuture which is returned by an I/O operation (i.e. write(..)).

The second way is to add a listener to the returned ChannelFuture.  Your
listener will be invoked when the operation is done.

I guess what you want is the first approach, right?  If so, please make
sure to add the ExecutionHandler to the pipline if you are going to call
await() or awaitUninterruptible() within the ChannelHandler.  Otherwise
you will never notified on completion (i.e. dead lock) because it is I/O
worker thread that notifies the completion and you are waiting for the
completion in *the* I/O worker thread without ExecutionHandler.

HTH,
Trustin
