      Compiling a rule like (*1) which is described in MVEL dialect and uses BigDecimal literal (number literal + suffix 'B') with executable rule models enabled, an error like (*2) occurs.

      (*1)

      package com.example.reproducer

import com.example.reproducer.Bus

dialect "mvel"

rule "bus3c"
    when
        $bus : Bus()
    then
        modify($bus) {
            weight = 13000B
        }
        System.out.println("***** " + $bus + ", weight = " + $bus.weight);
end

      $bus.weight is a BigDecimal type property.

      (*2)
