      Description

      We are using openjpa-2.0.1 with a thin wrapper inside apache-karaf.

      The wrapper essentially sets the context class loader to the class loader of the application bundle and then calls

      PersistenceProvider.createEntityManagerFactory(String emName, Map map)

      on the service exported by openjpa.

      We get an exception like cited at the end of this report, which is pretty much the same issue than OPENJPA-1491, where the exception occurred in the alternate method

      PersistenceProvider.createContainerEntityManagerFactory(PersistenceUnitInfo pui, Map m)

      The code in

      org.apache.openjpa.persistence.PersistenceProviderImpl.getBrokerFactory(PersistenceProviderImpl.java:148)

      reads

      BrokerFactory factory = getBrokerFactory(cp, poolValue, null);

      , which is exactly the same issue as in OPENJPA-1491, because the null CLassLoader causes the underlying code to use the context class loader, which is set to the class loader of the application and not the class loader of the openjpa bundle.

      Replacing the above mentioned line by

      BrokerFactory factory = getBrokerFactory(cp, poolValue, BundleUtils.getBundleClassLoader());

      would fix this issue as in OPENJPA-1491.

      (remark: BundleUtils.getBundleClassLoader() return null outside OSGi contexts, so this code works outside OSGi, too....)

      Best regards,

      Wolfgang
