Hello,

cglib (hibernate) throws strange exception with each hibernate session factory lookup in my enviroment, but my application works fine. Can someone help with that?

My enviroment is:
JDK 5.0
Sun Java System Application Server 8.1

Hibernate version: 2.1.8

Mapping documents: N/A

Code between sessionFactory.openSession() and session.close(): N/A

Full stack trace of any exception that occurs:

Name and version of the database you are using: Oracle 9i Database R9.2.0.6

It looks like you are trieng to serialize cglib stuff using "Unsafe" API, this stuff to serializes classes without constructor.

Baliukas,

sorry, I don't understand your answer. Could you provide more details?

I do NOT try serialize anything straight in my source code. I use Hibernate feature to store hiberante sassion factory into directory of my application server only. J2EE server is Sun Java System Application Server 8.1 running on JDK 5.0.

This problem is somewhere between Hibernate - CGLIB - SJSAS. I even don't know which layer throws mentioned exception.

best regards,
Radovan Sninsky

Ignore this error message, this message will be removed in the next release.
This stuff is related to internal optimizations in JVM ( it is something like "native reflection optimizer", so you can dissable cglib optimizer on this JVM to save memory )

How can I do that? I try , but everything works in same manner, appserver throws same exception.

Rado

Try to integrate cglib from CVS, I am not sure, but probably it will work with hibernate 2.1. It must not print this noise (it is not error, it is just a paranoid message).
Probably there is some setting to dissable factory serialization on SJSAS too.

Recently, I tried new maintenance release 3.0.1 of hibernate3 with new version of CGLIB 2.1.
Unfortunately, I have faced same "paranoid message" as last time with hibernate2 r2.1.8 and CGLIB 2.0.2.

Probably, this problem was not fixed in 2.1 release. Is there newer version of CGLIB not integrated with hibernate3, for now?

Yes, right.

Have you managed to have JNDI bound SessionFactory in SUN AS ?

I have some problems:
