Configurable LockType for JpaConsumer

Hi,

We are using the DB as a poor man's queue and we have two instances from our
application running. This means we have competing consumers.
By default the jpa consumer uses LockType.WRITE. Is it possible to configure
this to PESSIMISTIC locking? We call a legacy service which is not IDEM
POTENT causing some bugs in a backend system. Using pessimistic locking
solves this but it looks like we can not configure the jpa component to use
another LockType.

Kind regards,
Bart

Hi

Ah looks like we can add an option so you can configure this. Feel
free to log a JIRA ticket. And as we love contributions, you are
welcome to work on a patch.
