Changing javassist jar didn't work. I still receive the errors.
By the way, the exception is thrown by
"org.hibernate.tuple.entity.PojoEntityTuplizer".
Is there a incompatibility with the hibernate jars?
One more issue is that the logging level of the stack trace is in WARN
level. And I still haven't encountered anything weird in runtime.
