hibernate EntityManager malfunction in Oracle 10 G (OC4J)

When the

Code:

HibernatePersistence.createEntityManagerFactory(String emName, Map map)

is invoked to retrieve an EntityManagerFactory instance, the Hibernate configuration is loaded from a persistence.xml document using the following snippet:

Code:

Enumeration<URL> xmls = Thread.currentThread().getContextClassLoader().getResources("META-INF/persistence.xml");

Is it possible, this doesn't work within an Oracle OC4J container? (When I just use

Code:

URL xmls = Thread.currentThread().getContextClassLoader().getResource("META-INF/persistence.xml");

, the persistence.xml URL is returned (but this can't be used when there are different JARs). The ClassLoader.getResources() just returns an empty enum.
I know this isn't really your problem, but I'm just mentioning it, because this would mean that your EntityManager implementation isn't really usefull on an Oracle App Serv.

They probably have a broken classloader impelmentation. It'd be cool if you can push the bug to oracle. This is a very basic feature, not esp. related to EntityManager

Apparently, this bug was already filed by the JSF friends.
Fixed in release: 9.0.4.1 Bug ID: 3334337 Description: Method ContextClassLoader.getResources() returns incorrect results.
