[rules-users] Is 3.1 M1 backward compatible?

[Dandrea Francesco]

Hi all, 
the attached example runs ok (slow but ok) on JBoss Rules 3.0.5
Now when I run it with 3.1M1 I have an exception (I pasted it at the end
of the mail).
Is 3.1 M1 backward compatible? Is this a bug? Should I change the code
in some way?
Thanks a lot
