> The DRL code below results in TWO firings of rule exornot. (5.1.1: Only one firing) 
> declare Fact
>   x : int
>   y : int
> end
> rule ins
> when
> then
>     insert( new Fact( 1, 10 ) );
>     insert( new Fact( 2, 20 ) );
> end
> rule  exornot
> when
>     exists Fact( x == 1 )
>     or
>     not Fact( x == 2, y == 20 )
> then
>     System.out.println( "SUCCESS" );
> end
> NOTE: If field 'y' is removed from 'Fact' and the rule patterns, the rule fires still twice in 5.3.0, but also twice in 5.1.1.
