> According to the Java Persistence API 3.3.2 Transaction Rollback, the persistence context could be in inconsistent state after transaction rollback, which is suggesting to renew the EntityManager instance after transaction rollback. Actually I verified that if I renewed the EntityManager instance after rollback then camel-jpa could continue to work after that. I'll submit a pull request in a minute.
