JBoss AS 7 not using WEB-INF hibernate lib and throwing "Unknown service requested [org.hibernate.boot.registry.classloading.spi.ClassLoaderService]" - spring

Question

I'm migrating a Spring+Hibernate application from Weblogic 12c to JBoss AS 7, and I'm getting the following error:
20:07:47,395 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-1) MSC00001: Failed to start service jboss.persistenceunit."connecta-presenter-2.2.1.war#ConnectaPresenterPU": org.jboss.msc.service.StartException in service jboss.persistenceunit."connecta-presenter-2.2.1.war#ConnectaPresenterPU": Failed to start service

The Unknown service requested [org.hibernate.boot.registry.classloading.spi.ClassLoaderService] message thrown by line 126 of org.hibernate.service.internal.AbstractServiceRegistryImpl is an exception thrown only in version 4.0.1 of Hibernate Core, which is the version that is in my JBoss AS 7 modules folder.
The thing is that my application uses Hibernate 4.3.10, and this specific line doesn't exist more in this version (I could see comparing the source code on Github).
The following documentation on JBoss AS 7 site states that when you migrate from Weblogic to JBoss:
https://docs.jboss.org/author/display/AS72/How+do+I+migrate+my+application+from+WebLogic+to+AS+7#HowdoImigratemyapplicationfromWebLogictoAS7-Migrateweblogic.xmlDescriptorFileConfigurations
So there's no such code as the following in jboss-web.xml file:
<prefer-application-packages>
<package-name>javassist.*</package-name>
</prefer-application-packages>
It says that JBoss always uses WEB-INF/classes and WEB-INF/lib before the internal modules.
Any idea of what's happening?

If you want to use your own specific version of Hibernate (or any other service/software for that matter), you can do that instead of depending on JBoss AS 7 modules.
Create a new folder structure, say org/myhibernate/main in your $JBOSS_HOME\modules\system\layers\base\ directory. Put the needed jar (say my.jar) in the main folder and create a module.xml file like this:
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="org.myhibernate">
<resources>
<!-- Modules -->
<resource-root path="my.jar" />
</resources>
<dependencies>
<module name="javax.api"/>
<module name="sun.jdk"/>
</dependencies>
</module>
Now create a jboss-deployment-structure.xml in your EAR/web folder in your workspace and include this dependency -
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
<sub-deployment name="yourfile.war">
<dependencies>
<module name="org.myhibernate" />
</dependencies>
</sub-deployment>
</jboss-deployment-structure>
