BD-J Code ossification on replicas?

Is it possible to protect our custom BD-J code on new titles that are replicated at all?
Given the content is protected with AACS, I would have thought that our custom BD-J code can also be ossified to prevent others stealing our development but really have no idea how to go about it. I have also written to Sony DADC to see what they have to say, but have yet to hear back from them - our current project is near completion & we do not want to send it to replication unprotected.

Any ideas anybody?

As far as I can tell by breaking AACS your code BD-J code becomes public. I'm not sure if there is an additional way of protecting it.

I am not sure that is correct - BD-J code can usually be read simply by loading the disc into a BD-ROM drive. We have done this on several replicated discs.
We think we have found a way though - Allatori Java Obfuscator
and my code writer is working with their developers to ensure we pass both Eclipse checks as well as the Sony AF verification checks.
