Hi,
I think this is not really a bug, rather behaviour specified by JBI + 
the way seda flow works.
JBI 5.5.2.1.3: the exchange should be set to ERROR status - this is
relevant note around line 500 of DeliveryChannelImpl

Under heavy load following scenario can occur:
- you do sendSync with timeout
- the exchange stucks is seda queue
- it times out - it is marked as timed out (aborted) - and JBI spec says
it cannot be dealt with anymore
- the message is taken from seda queue by destination endpoint - and
when it tries to do sth with it (e.g. do channel.doSend()...) - error 
is thrown.

The point is that destination endpoint should be aware that sender 
does no longer wait for result

br,
maciek
