The WildFly/AS7 JPA container/deployer automatically adds the Hibernate 
ORM module to the application classpath.  However, this doesn't help 
Hibernate native applications.

With OSGi, there is no automatic solution, applications are expected to 
add Javassist to the application classpath.

In other environments, Hibernate applications also need Javassist on the 
classpath but the other environments are more likely to add Hibernate + 
Javassist jars to their global classpath.

No silver bullet here.
