> 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:
