Robbie Gemmell updated QPIDJMS-357:
-----------------------------------
Description:
The "client acknowledgement" session acknowledgement mode allows for messages
to be received by the application and for an explicit acknowledgedment step to
then be perfomed later after processing through calling Message#acknowledge().
Confusingly however, this does not acknowledge the specific message it is
called on but rather every message received on the same Session as the message
since the prior such call. Although this is clearly documented in the API docs,
many users are confused by this behaviour and understandably expect that
calling message#acknowledge() would only affect that specific message. Several
implementations provide a different session ack mode value to instead configure
sessions for this expected 'individual acknowledgement' behaviour, such that
only the message upon which acknowledge() is called is affected, and this was
also under discussion for inclusion in JMS 2.1. We should provide this useful
functionality.
The integer session acknowledgement mode value used is 101.
