1. Re: Why are so many classes/methods "final" or "private"?
adamw Feb 8, 2012 8:08 AM (in response to brettreyno)Hmm probably an experiment on my side with some coding style. Feel free to submit patches which remove those and make the code more easy to extend
What elements does not Envers support?

brettreyno Feb 8, 2012 9:11 AM (in response to adamw)Thanks, that's good to know. :-)
The two main issues I've encountered so far are:
- Envers doesn't appear to support Hibernate's CustomCollectionType; CollectionMetadataGenerator's addMapper() method has a series of instanceof checks to determine what sort of collection a property is, but if it's a CustomCollectionType, it falls through to the line throwing the UnsupportedTypeException.
- Envers also doesn't appear to work with the Interceptors to create objects when you attempt to recover an old version of an audited object. Our application maps Interfaces rather than Classes, using a custom Interceptor to call a Factory method rather than an object's constructor, but Envers just assumes a default constructor exists. Since Interfaces don't have constructors, it crashes trying to rebuild these objects.
There's another issue we've found, but I haven't yet determined if it's a problem with how we're doing things or something missing in Envers, but either way we'll get it sorted out. Thanks!
Edit: Again, this is all as of Hibernate 3.6.9 - has any of this been addressed in 4 yet?

3. Re: Why are so many classes/methods "final" or "private"?
brettreyno Feb 8, 2012 5:08 PM (in response to brettreyno)To add on to my first bullet there, it seems as though it doesn't work with ArrayType or IdentifierBagType either, and both OrderedSetType and OrderedMapType are only supported through their superclasses (SetType and MapType).
I think I've worked out a way to resolve these issues, however it'll probably be some time until a patch is submitted due to my company's code review procedures with regards to FOSS.

4. Re: Why are so many classes/methods "final" or "private"?
adamw Feb 14, 2012 8:00 AM (in response to brettreyno)Nope, none of this is addressed in 4. As I see hopes for the Interceptor case, it probably will be worse with custom collections - possible a fix would require to provide a mechanism for providing a custom-audit-collection implementation. But maybe not
I hope you'll manage to get through your company's FOSS policy
