Jason Novotny commented on HHH-2317:
------------------------------------

My test case is a bit complex. I'm using Tomcat and I have my hibernate libs in the WEB-INF/lib of my web application. However I have a "service factory" that lives in the Tomcat shared/lib classpath which maintains an instance of my hibernate persistence wrapper. The persistence wrapper passes itself to the service factory along with its classloader. Now in web application B, I get an instance of my persistence wrapper and I use it to load in the hibernate mapping files in webapp B. As long as lazy="false" it works fine. Otherwise if lazy is true, I get this stack trace:
