Description copied from interface: MessageContainerManager
This is a hook to notify the dispatcher for the clients subscription that we have acknowledged a message within a transaction but before the commit - so the message is not really being acknowledged here but this method is intended to be a hook to let the dispatcher know that we can now send another message to the client.

Without this hook, if we have a prefetch value of 1, we can never consume 2 messages in a transaction, since the ack for the first message never arrives until the commit()

Parameters:
client -
transactionId -
ack -

JMSException
