Exec model compilation fails when comparing BigDecimal and String

KJAR build fails with executable model when comparing BigDecimal type and String type property like the following.

rule "rule_compare_bd_and_str"
    no-loop true
    when
        $fact : Fact( $bd: bd )
        $code : Code( id == $bd )
    then
        System.out.println("***** $fact = "+$fact+", $code = "+$code);
end

In Fact class, bd is BigDecimal type property.
In Code class. id is String type property.

Executable model build fails with the following error:

[ERROR] Failed to execute goal org.kie:kie-maven-plugin:7.59.0.Final-redhat-00006:generateModel (default-generateModel) on project kjarCreation: Execution default-generateModel of goal org.kie:kie-maven-plugin:7.59.0.Final-redhat-00006:generateModel failed: [com/example/reproducer/P22/LambdaExtractor22353C40A1384D56E5C5AEF7CBBEECB5.java (25:858) : Cannot cast from BigDecimal to String] -> [Help 1]

and here is the problematic generated source code which causes above ERROR.

@Override()
public java.lang.Object apply(java.math.BigDecimal $bd)

Non-executable model build succeeds with above rule.
In addition, executable model build also succeeds with version 7.11.1.(7.52.0.Final-redhat-00008)
