Sangjin Lee closed ASYNCWEB-32.
-------------------------------

    Resolution: Fixed

Fixed.  If there is any unexpected exception in the FutureListener, it is 
propagated to the waiting response future.

> any unexpected exception in FutureListener.operationComplete() is silently 
> swallowed

> Occasionally we see unexpected exceptions happening in 
> AsyncHttpClient$FutureListener.operationComplete().  For example, 
> Socket.setIntOption() may fail unexpectedly occasionally.
> When they do, the exception from operationComplete() gets caught by Mina's 
> default exception monitor.  The behavior of this default monitor is to log a 
> warning and eat up the exception.  As a result, the particular request is 
> aborted.
> This has a particularly serious consequence if the caller uses a future to 
> wait for the response.  Although the request is aborted, the future is never 
> completed by anyone.  If there is an unexpected exception, the future should 
> be immediately completed with the exception.
