Claus Ibsen commented on CAMEL-4668:
------------------------------------
Its 2 different things:
1: The template send 3 messages to INSERT data into the database.
2: Then the route is started, which starts the consumer, it then pickup the 3
messages. And fail processing the last message. Which forces all 3 to rollback.
So when it poll again, it find the 3 messages, and try again etc.
> JpaConsumer - Should rollback if processing of an exchange failed

> If a JPA consumer pickup X messages and then one of those messages fails to
> be processed and throws an exception, then the JPA consumer should detect
> this and mark the TX as rollback.
> Currently there is a flaw which causes the JPA consumer to commit the batch.
