Comment 2 Martin Basovník 2014-10-22 10:19:02 UTC 
Better reproducer:
1. features:install -v switchyard-quickstart-camel-jpa-binding
2. Check if it works (log:display), if so continue in step 3
3. osgi:refresh <ID-switchyard-camel-jpa-binding>
4. log:display -> you will get reported error

See: https://github.com/jboss-switchyard/release/blob/2.0.0.Alpha3/karaf/features/src/main/resources/features.xml#L470

If I have already installed bundle 'hibernate-osgi' and I try to install a switchyard application with JPA support, it fails. Then I have to refresh 'hibernate-osgi' bundle to register 'EntityManagerFactory' service.

Moreover, my bundle will not have registered service 'SwitchYardContainer'. So I have to stop my bundle and restart it. 'Switchyard-deploy' bundle will then register this service. 

I think that there can be also problem with ordering of registration of services 'EntityManagerFactory' and 'SwitchYardContainer'.

Resetting the flags back to the state it was before Oct-24- 2PM. There was an incorrect bulk update that I'm trying to fix.

I don't know if this can be fixed as hibernate-osgi needs to be installed/activated after the bundle using jpa.  This issue may be corrected in the newer version of Karaf/Hibernate as Karaf 2.4 provides a hibernate jpa feature.
