Message loss when server is killed during msg.acknowledge()

When server is killed when HornetQ server stored ack to journal but did not finish QueueImpl.postDeliver() method then message is lost.

Test scenario:

1. Start EAP server with HornetQ and queue InQueue
2. Install byteman script [1] - "kill server when x-th message is being acknowledge"
3. Send messages to InQueue
4. Read messages from InQueue with standalone client using CLIENT_ACKNOWLEDGE mode for session (each message is acknowledged)
5. Restart server
6. Read rest of messages

Result:
1 message is not delivered
client gets exception from msg.acknowledge() and ends

Byteman script:

RULE setup counter
CLASS org.hornetq.core.server.impl.QueueImpl
METHOD <init>
AT EXIT
IF TRUE
DO createCounter("counter")
ENDRULE

RULE info about incrementing counter
CLASS org.hornetq.core.server.impl.QueueImpl
METHOD postAcknowledge
AT INVOKE org.hornetq.core.persistence.StorageManager.deleteMessage(long)
IF TRUE
DO incrementCounter("counter");
System.out.println("Called acknowledge message - kill between - ack saved to journal (commited) and deletion of message " + readCounter("counter"))
ENDRULE

RULE kill on receive
CLASS org.hornetq.core.server.impl.QueueImpl
METHOD postAcknowledge
AT INVOKE org.hornetq.core.persistence.StorageManager.deleteMessage(long)
IF readCounter("counter")>123
DO System.out.println("Byteman invoked"); killJVM();
ENDRULE

It seems to be a quality issue for our HornetQ component.

Thank you,
