HI Martin,

The message is confirmed, at least I know that the confirm method is 
called. From my logs I can see that after I call confirm, the 
JournalProtocol$DeleteMessages message is sent. Also, if confirm would not 
work I would expect the second run to fail, as the messages would also be 
replayed there.

I will try to recreate the problem with a failing test.

Cheers,
Michael
