Description

camel-jpa producer does not reuse the existing EntityManager in transaction and create its own one.

This happens when JpaTransactionManager is used. It creates an EntityManager for transactions in the doBegin() method.
So there will be two EntityManagers and two connections even if there is only one route for the jpa producer.
