Arithmetic operation with bind variable of BigDecimal type in constraint fails in executable model build

Solution Verified - Updated -

Issue

A build of the following rule fails with executable model.

dialect "mvel"

rule "rule_multiply"
    when
        $fact : Fact( $bd: bd, bd2 == $bd * -1)
    then
        System.out.println("***** $fact = "+$fact);
end

This fails with :

Execution default-generateModel of goal org.kie:kie-maven-plugin:7.59.0.Final-redhat-00009:generateModel failed: [
com/example/reproducer/PCD/LambdaExtractorCD1B6E5C7CFD387685758203C8EB22B1.java (25:858) : The operator * is undefined for the argument type(s) BigDecimal, int,
com/example/reproducer/PF0/LambdaPredicateF08177C575A8F93768627585DF0FD322.java (25:1107) : The operator * is undefined for the argument type(s) BigDecimal, int]

This does not happen when building with non-executable model.
