Oggetto: Re: [rules-users] Is 3.1 M1 backward compatible?

The syntax is backwards compatible. However as the release notes mention we no longer autobox primitives, as you can now work directly with them, which will cause issues in  old drls that assumed numbers are wrapped. Also pojos must have a default constructor and not use the final keyword at the class and method level - we are actively looking to add more flexability to this case.

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
