> Key: DIRMINA-574
> URL: https://issues.apache.org/jira/browse/DIRMINA-574
> Project: MINA
>  Issue Type: Bug
>  Components: Core
>Affects Versions: 1.0.10, 1.1.7, 2.0.0-M1
>Reporter: Trustin Lee

> Steps to reproduce:

> 2) A user writes a message.
> 3) the message is encoded by a ProtocolCodecFilter.
> 4) MINA notices the closed socket and fires a sessionClosed event.
> 5) After the sessionClosed event is fired, IoFilterChain.clear() is called.
> 6) MINA tries to write the user write request, but the session is closed 
> already - all write requests are discarded.
> 7) Before MINA discards all write requests, MINA checks if the first item in 
> the queue is an empty buffer, which means a special separator which is 
> handled by ProtocolCodecFilter.
> 8) If there's an empty buffer in the head of the queue, MINA fires a 
> messageSent event with the empty buffer in the hope that ProtocolCodecFilter 
> will catch it.
> 9) However, the filter chain is empty and therefore IoHandler implementation 
> gets ClassCastException.
> A possible workaround is just to ignore the exception, but we need to provide

Will be fixed when the MessageSent message will be removed, something that 
can't be done for 2.0

Priority: Blocker  (was: Minor)

raised to blocker, as the underlaying logic used to handle selected keys is 
flawed.

> Steps to reproduce:

> 2) A user writes a message.
> 3) the message is encoded by a ProtocolCodecFilter.

> 5) After the sessionClosed event is fired, IoFilterChain.clear() is called.
> 6) MINA tries to write the user write request, but the session is closed

> 7) Before MINA discards all write requests, MINA checks if the first item in 
> the queue is an empty buffer, which means a special separator which is 
> handled by ProtocolCodecFilter.
> 8) If there's an empty buffer in the head of the queue, MINA fires a 
> messageSent event with the empty buffer in the hope that ProtocolCodecFilter
