My bad. To turn off cglib you need to set it as a system-level property.
java -Dhibernate.cglib.use_reflection_optimizer=false
http://www.hibernate.org/hib_docs/v3/reference/en/html/session-configuration.html#configuration-misc-properties
hibernate.cglib.use_reflection_optimizer=false
Enables/disables use of CGLIB instead of runtime reflection (System-level
property). Reflection can sometimes be useful when troubleshooting, note
that Hibernate always requires CGLIB even if you turn off the optimizer. You
can not set this property in hibernate.cfg.xml.

Set this in hibernate.properties, as a java system property, or by calling
Configuration#setProperty() directly.
You can postpone the problem a bit using the java command flag
-XX:MaxPermSize.
e.g. from http://www.caucho.com/support/resin-interest/0512/0022.html
