Description

We should try to avoid storing headers with are transient such as JpaEntityManager and other kinds. But instead allow access to them using a JpaMessage type that has a getter method to it,

Then ppl can access it using

EntityManager em = exchange.getIn(JpaMessage.class).getEntityManager();

See SO for a problem when using as a header
