    Description

      Compiling a rule like (*1) which is described in MVEL dialect and uses an expression like BigDecimal_type_property = BigDecimal_type_property.divide(BigDecimal_value), for example (*1-1), with executable rule models enabled, an error like (*2) occurs.

      This issue occurs in the case of using the other basic operation add, subtract and multiply as well as divide.

      (*1)

      package com.example.reproducer
      
      import com.example.reproducer.Bus
      import java.math.BigDecimal
      
      dialect "mvel"
      
      rule "bus3d"
          when
              $bus : Bus()
          then
              $bus.weight = $bus.weight.divide(BigDecimal.valueOf(1000));    ..... (*1-1)
              System.out.println("***** " + $bus + ", weight = " + $bus.weight);
      end
      

      $bus.weight is a BigDecimal type property.

      (*2)
