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.<br>

<pre wrap="">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
