Hi Mihael,
difficult to say without the actual source.
The problem occurs when the coordination ends. So maybe this happens in
a different thread.
See
https://osgi.org/javadoc/r5/enterprise/org/osgi/service/coordinator/Participant.html#ended%28org.osgi.service.coordinator.Coordination%29
"Participants are required to be thread safe as notification can be made
on any thread. "
Can you paste the relevant code snippets of SalesProspectResource.update?
It might also help to update to the new Aries JPA 2.2.0 version. (Would
be a bigger switch though).

Hi,
I got a rest service where I am using multiple persistence units and
data sources to store data in different databases using multiple
transactions (I don't need all in one transaction). It all happens on
multiple threads.
I am getting an exception on the last persist where I want to save
some log in a database which happens on the same thread where the rest
service starts (qtp18495206-81) . It seems that the EntityManager is
cleared up before my call to persist. Is that the reason for the
exception?

I am using transaction attribute "Required".
I am running Apache Karaf 3.0.3 with Aries JTA and OpenJPA 2.2.2.
Thanx in advance for any help or hint.
