Sorry, my mistake. My classes uses proxy. Why proxy with this class cannot be used with 2.1beta4? It worked perfectly in 2.1beta3 and before.

Description:
I have some persistent classes, which cannot be instrumented with CGLIB reflection optimizer. In Hibernate versions prior to 2.1beta4 I've got the following correct log messages and everything worked fine:
---
14:26:48,230 INFO [:] SessionFactoryImpl:109 - building session factory
14:26:57,507 INFO [:] ReflectHelper:328 - reflection optimizer disabled for: si.marand.maf.server.jastreb.party.module.entity.PersonEntity, NullPointerException: null
14:26:59,175 INFO [:] ReflectHelper:328 - reflection optimizer disabled for: si.marand.maf.server.jastreb.party.module.entity.BankEntity, NullPointerException: null
14:27:06,349 INFO [:] SessionFactoryObjectFactory:86 - Factory name: maf-server-hibernate-sessionFactory
---

But in version 2.1beta4 is instead of this in the same phase of startup process thrown an exception, which stops application. The excerption from log it here:
---
12:18:51,464 ERROR [:] LazyInitializer:62 - CGLIB Enhancement failed

        ...

Besides of this bug it seems, that hibernate.cglib.use_reflection_optimizer setting is ignored in beta4 and "true" is allways used as it's value.
