How to fetch enumeration from KieBase programmatically?

Issue

What problem/issue/behavior are you having trouble with? What do you expect to see?

    Collection<KiePackage> kPackages = kSession.getKieBase().getKiePackages();
    for (KiePackage nextPackage : kPackages) {
        Collection<Rule> rules = nextPackage.getRules();
        for (Rule nextRule : rules) {
        RuleImpl r = (RuleImpl) nextRule;
        System.out.println(" ------------------ ");
        System.out.println("Package: " + r.getPackageName() + " - Rule Name: " + r.getName() + " - Dialect: " + r.getDialect());
        }
    }

Using above code it is possible to access rules but not an enumeration (created in business-central) inside a package.
