Albert Lee closed OPENJPA-1910.
-------------------------------
Close issue in preparation for 2.2.0 release.
> openjpa uses application ClassLoader for resolving BrokerFactory (revisited)
> ----------------------------------------------------------------------------
>
> Key: OPENJPA-1910
> URL: https://issues.apache.org/jira/browse/OPENJPA-1910
> Project: OpenJPA
> Issue Type: Bug
> Components: osgi
> Affects Versions: 2.0.1, 2.1.0, 2.2.0
> Environment: apache-karaf 2.1.0, openjdk-1.6.0b18
> Reporter: Wolfgang Glas
> Assignee: Rick Curtis
> Fix For: 2.1.0, 2.2.0
>
>
> 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,
