Asankha C. Perera resolved SYNAPSE-98.
--------------------------------------
Resolution: Fixed
Axiom UUIDGenerator is not thread safe, and generates duplicate message ID's causing Synapse to loose the callbacks for messages. The reason why this was not seen earlier is because with RC2 - Synapse is even faster to catch issues like this :-)
As we possibly cannot wait till the next Axiom/Axis2 releases for this fix, I am creating a new Synapse UUID generator.
Chathura found this issue with Axiom, and will file a defect with them for its resolution.

> Reported by Paul as:
> When I load up Synapse I'm seeing the following error:
> [HttpClientWorker-3] WARN SynapseCallbackReceiver - Synapse received
> a response for the request with message Id :
> urn:uuid:7CD39BD337DE2BBBCD1178099875927 But a callback has not been
> registered to process this response.
> Under light load it doesn't happen but the more you load the more of
> these messages I get. When this happens the response never comes back
> to the test client. When I ran 1000 hits from 20 concurrent clients,
> 38 of them got lost this way.
