> For reasons discussed on the [openjpa-user MailingList|http://mail-archives.apache.org/mod_mbox/openjpa-users/201411.mbox/%3CCALLZsMnXPQT%2BeQB3VjYe4U05%2BgSR%2Bw37QqXGRdxdvM-kgEXdLw%40mail.gmail.com%3E] I need to use a custom BrokerFactory in an OSGi environment.
> My custom BrokerFactory is obviously in my own OSGi bundle, not in the official OpenJPA bundle. Now, due to OPENJPA-1491 {{org.apache.openjpa.kernel.Bootstrap}} (in connection with {{org.apache.openjpa.persistence.PersistenceProviderImpl.createContainerEntityManagerFactory(PersistenceUnitInfo, Map) and org.apache.openjpa.persistence.osgi.PersistenceActivator.getBundleClassLoader()), my BrokerFactories can only live in the official OpenJPA bundle, so that my custom BrokerFactory is not found.
> In my opinion it would be better if {{org.apache.openjpa.persistence.osgi.PersistenceActivator.getBundleClassLoader()}} would return a ClassLoader not only delegating to openjpa´s bundle but _in addition_ (as a fallback) to the {{PersistenceUnitInfo}}´s bundle.
> That way one would be able to use arbitrary BrokerFactories by importing them if required to the bundle where {{persistence.xml}} is defined.
