There was a problem with CGLIB proxies much similar to this... so
probably the same problem.
What happens is that to shadow a fact, drools needs to extend the actual
class being asserted, and override the equals and hashcode methods. So, the
class can't be final, nor these methods can be final. Previously I wasn't
checking for final on these methods and that was the reason for the error.
I fixed that in trunk. It means, if XML Beans are generating methods
equals/hashCode as final, drools won't be able to shadow them (and so will
automatically disable shadowing for them), but it will not raise the error
anymore.
Let me know if it is still a problem for you in trunk.

All this sounds eerily similar to the problem I am reporting. In the
4.0version I am getting the following exception on those inner classes:
Exception in thread "main" java.lang.VerifyError: class

The catch is that XML Beans objects are auto generated based upon and XSD
and we have limited control over what gets generated.
