Hello,

I just migrated to Hibernate 2.1 beta3 and I am getting an error when I try to save an object that contain collections:

net.sf.hibernate.AssertionFailure: Hibernate has a bug processing collections

It says Hibernate has a bug. I think it is only a 2.1 version problem because it didnt occur when I used 2.0.3. However Id like to migrate because I wanna use 2.1 new features.

Is it really a bug or that i something i could do?

Thank you,

Could you submit the code (as a simple main() method) to JIRA. It may be a bug, or it might be you doing something 'wrong', but either way, I still need to know about differences b/w 2.1 and 2.0.


This is why we do betas ;)

Hello Gavin,

I can't think a way I could reproduce it in a single main(). There are too many classes and database tables associated.

Well, then you'll understand if I absolutely disbelieve that Hibernate has a bug then?

All bugs are reproduceable.


If this only occurs in a situation that is too complicated to reproduce in a main() method, then quite clearly you havn't tried to isolate the problem _at_all_, and it is far more likely that your own over-complicated code is responsible.

Isolating problems is the *first* thing you do, before posting here.

P.S. The most likely cause of this is that you caught an exception that occurred buring flush(), and then continued to use the session.

I will try to isolate. The problem is that I have a huge class hierarchy with many branchs and composite ids. I had to do it because im working in a pre-made database. I cant modify it. I will try to make null the branchs not associated with the problem, modifying current mappings. I hope it do not create other problems. :-|

You haven't replaced commons-lang 1.0 with 2.0 have you? I find the same error when I use version 2.0 without having 1.0 in the classpath too.
