Binding a list written in MVEL expression like (*1-1) causes a build error like (*2) in executable model.
This issue does not occur in build with executable model disabled.

(*1)

package com.example.reproducer

import com.example.reproducer.Car

dialect "mvel"

rule "rule12a"
    when
        $car : Car( $group : ["compact", "medium", "luxury"] )    // ..... (*1-1)
    then
        System.out.println("***** Which group " + $group + " is " + $car + " categorized into?");
end

(*2)
