      Building a rule written in MVEL dialect like (*1) using BigDecimal_variable % Numeric_value operation (*1-1) in executable rule model, a compilation error (*2) occurs.

      (*1)

      package com.example.reproducer

import com.example.reproducer.Fact

dialect "mvel"

rule "rule1b"
    when
        $fact : Fact( $year : year, (($year % 400) == 0) || ((($year % 4) == 0) && (($year % 100) != 0)), $flag : "YES" )    // ..... (*1-1)
    then
        modify($fact) {
            leapYear = $flag
        }
        System.out.println("***** $fact: " + $fact + ", " + $year + " is a leap year? " + $fact.leapYear);
end

      (*2)

      [ERROR] /work2/testdir/reproducer_mc_1b/target/generated-sources/drools-model-compiler/main/java/com/example/reproducer/PF6/LambdaPredicateF6282A65CE56BF77478DD6D1D7E1AFE4.java:[17,133] bad operand types for binary operator '%'
