      Compiling a rule like (*1) which is described in MVEL dialect and contains an assignment statement to BigDecimal type property with executable rule models enabled, compilation errors like (*2) occur.

      (*1)

      package com.example.reproducer

import com.example.reproducer.Bus

dialect "mvel"

rule "bus3a"
    when
        $bus : Bus()
    then
        modify($bus) {
            weight = 13000
        }
        System.out.println("***** " + $bus + ", weight = " + $bus.weight);
end

      $bus.weight is a BigDecimal type property.

      (*2)
