Major Description
Today, it looks much better [1]. We are trying to fix the unit tests which are failing from time to time on slower boxes. But this isn't so easy for all of them...
I had a look at org.apache.camel.processor.jpa.JpaProducerConcurrentTest.testConcurrentProducers. A few times I get the following exception which results in missing exchanges in the mock:result endpoint:
2013-10-11 14:01:10,623 [pool-2-thread-2] ERROR DefaultErrorHandler - Failed delivery for (MessageId: ID-christians-macbook-pro-fritz-box-54975-1381492869188-0-4 on ExchangeId: ID-christians-macbook-pro-fritz-box-54975-1381492869188-0-9).

which is throwing from the line 55 in org.apache.camel.component.jpa.JpaProducer
entityManager.joinTransaction();
I think this is a concurrency issue we have to investigate (not sure whether the issue is in Camel, Spring, OpenJPA, ...).
