Thanks a lot, Edson, for the quick reply yesterday. Here's another one. The following rule compiles, but Drools crashes upon insertion of an object. Same when calling a static method instead of a constructor.

(Based on the Eclipse sample rule project)

rule "rule1"
        when
                $p1:Message(
                        message in (
                                (new String("A")),
                                (new String("B"))
                        )
                )
        then
                System.out.println("foo");
end

I'm on drools 4.0.2 and mvel14-1.2.8.
