The default in 5.1 is the AMQ Message Store - which we recommend for
general purpose message persistence.
So it would be easier not to set any persistence adaptor in your
configuration to get started ;)

I'd like to get some sort of confirmation that I'm (not) "doing it

before posting this to JIRA, since I'm just a beginner with AMQ
(5.1.0).
I started having trouble with kaha persistence and after banging my
head to
the wall couple of times I re-read the documentation.
I think default amq persistence adapter is enough but there is still
<http://activemq.apache.org/kaha-persistence.html> that I stumbled
upon
first and after wards noticed that kaha is provided by default
<http://activemq.apache.org/amq-message-store.html>.
If I configure amq persistence adapter via spring as per document
above it
too will miss some of the configuration.

AMQPersistenceAdapter by default via

Here
are broker name and data directory plus task runner factory derived

broker (service) as default values. Actual configuration is done by
the
AMQPersistenceAdapterFactory itself some more default values to the
persistence adapter.
What kaha persistence adapter is missing first is the broker name.
