    Description

      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)

          Bug - A problem that impairs or prevents the functions of the product. DROOLS-5891 The use of BigDecimal literal causes a build failure in executable model.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
