JPA Container BundleDelegatingClassLoader should look for classes in the provider bundle, too
---------------------------------------------------------------------------------------------

                 Key: ARIES-681
                 URL: https://issues.apache.org/jira/browse/ARIES-681
             Project: Aries
          Issue Type: Bug
          Components: JPA
    Affects Versions: 0.3
         Environment: Glassfish 3.0 (EclipseLink 2.0.2), Glassfish 3.1 (EclipseLink 2.2)
            Reporter: Balazs Zsoldos


Currently the BundleDelegatingClassLoader in JPA container only looks for classes in the bundle
of the entitymanager. However the JPA implementation Eclipselink needs some classes from itself.
The reason is that in entity classes the properties that hold mapping of One-To-Many are converted
to EclipseLink list type. See the following exception stacktrace:
