I'm closing this as I believe this isn't a issue on newer versions of Drools. Please reopen if this is a bug on 5.2

> This is a problem with Drools 4.0.7, it does not happen in Drools 5:
> $factB.f1 is triggering a scenario where the engine creates an implicit biding to the "f1" field. 
> That in conjunction with the use of "or" is triggering the problem
> rule "implicit bindings test"
>     when
>         FactA()
>         $factB : FactB( $fB : f1 )
>         (not FactC( f1 == $factB.f1 ) or FactC() )   
>     then
> end
> The exception thrown is:
> java.lang.ClassCastException: com.sample.FactAShadowProxy cannot be cast to com.sample.FactB
