> Reproducing the problem:
> * Receive two messages via STOMP on a subscription with ack:client-individual
> * Start a transaction
> * Acknowledge message #2
> * Acknowledge message #1
> * Commit the transaction
> Expected behaviour:
> * Both messages are acknowledged, life goes on
> Observed behaviour:
> * Exception is raised
> {{javax.jms.JMSException: Unmatched acknowledge: MessageAck {commandId = 0, responseRequired = false, ackType = 2, consumerId = ID:(...)-6:555:-1:1, firstMessageId = null, lastMessageId = ID:(...)-6:555:-1:1:1, destination = queue://(...), transactionId = null, messageCount = 2, poisonCause = null}; Expected message count (2) differs from count in dispatched-list (1)

> I have prepared a [unit test|https://github.com/Anthchirp/activemq/commit/7df4f25975c6500e65b1688ca81e761c1825a32a] for this ([patch file|https://github.com/Anthchirp/activemq/commit/7df4f25975c6500e65b1688ca81e761c1825a32a.patch]).
> The exception is not raised if the messages are acknowledged outside of a transaction.
