/**
* Tests if javassist instrumentation is done with the proper classloader for entities with proxy class. The classloader
* of {@link HibernateProxy} will not see {@link IPerson}, since it is only accessible from this package. But: the
* classloader of {@link IPerson} will see {@link HibernateProxy}, so instrumentation will only work if this classloader
* is chosen for creating the instrumented proxy class. We need to check the class of a loaded object though, since
* building the configuration will not fail, only log the error and fall back to using the entity class itself as a
* proxy.
