Thanks for reporting.
Anytime :)
Here is one more fact that I learned from this example - messages in
mailboxes are not preserved by processors, correct? That is a message
is not saved until it is picked up by Receive handler.
Yes, when a processor's receive is called with a Persistent message, you
can be sure that is has been successfully persisted. On persistence
failure, a PersistenceFailure message is received instead.
And to make sure messages that don't make it to Receive handler by the
time of failure are preserved I must use a persistent channel, correct?
In general, a reply from a processor indicates to a Persistent message
sender that the message has been successfully persisted. If the sender
gets a reply from handling a PersistenceFailure message or no reply
(timeout), it has to resend the Persistent message.
There are numerous ways (impl options) for resending messages. Using a
channel is only one.
