Получение неправильного формата класса в Drools при использовании статического метода в RHS-части файла drool

В настоящее время я пишу правило для проверки дубликатов записей сотрудника.У меня есть EmployeeCache для хранения данных сотрудника в Map как идентификатор сотрудника в качестве ключа и объект Employee в качестве значения, когда запись не найдена.

Я использую версию drools engine 5.6 и имею JDK 1.8 и Springboot 2.5 и использование Intellij IDE версии 2018.

Ниже приведены зависимости, которые я использую, 

     <dependency>
        <groupId>org.drools</groupId>
        <artifactId>drools-core</artifactId>
        <version>5.6.0.Final</version>
    </dependency>
    <dependency>
        <groupId>org.drools</groupId>
        <artifactId>drools-compiler</artifactId>
        <version>5.6.0.Final</version>
    </dependency>

Ниже приведены мои файлы классов и файл правил,

//Класс pojo сотрудников, 

public class Employee {
private String name;
private Double salary;
private String department;
private Integer id;

public Integer getId() {
    return id;
}

public void setId(Integer id) {
    this.id = id;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public Double getSalary() {
    return salary;
}

public void setSalary(Double salary) {
    this.salary = salary;
}

public String getDepartment() {
    return department;
}

public void setDepartment(String department) {
    this.department = department;
}

}

// Класс обслуживания EmployeeCache, 

public class EmployeeCache {

private static Map<Integer,Employee>  employeeDetails = new HashMap<>();


public static void setEmployeeDetails(Integer empId, Employee employee){
    employeeDetails.put(empId,employee);
}

public static Map<Integer,Employee> getEmployeeDetails(){return employeeDetails;}
}

Это мое основное приложение для весенней загрузки, в котором я указал базы знаний и KnowledgeBuilderобработать правило. 

@SpringBootApplication
public class Springmicroservice1Application implements CommandLineRunner {
private static final Logger log = LoggerFactory.getLogger(Springmicroservice1Application.class);
Logger logger = LoggerFactory.getLogger(Springmicroservice1Application.class);

public static void main(String args[]) {
    SpringApplication.run(Springmicroservice1Application.class);

    final KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
    // this will parse and compile in one step
    kbuilder.add(ResourceFactory.newClassPathResource("testRule.drl", Employee.class), ResourceType.DRL);
    // Check the builder for errors
    if (kbuilder.hasErrors()) {
        System.out.println(kbuilder.getErrors().toString());
        throw new RuntimeException("Unable to compile \"accountValidation.drl\".");
    }
    // get the compiled packages (which are serializable)
    final Collection<KnowledgePackage> pkgs = kbuilder.getKnowledgePackages();
    // add the packages to a KnowledgeBase (deploy the knowledge packages).
    final KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
    kbase.addKnowledgePackages(pkgs);
    final StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();

    Employee employee = new Employee();
    employee.setDepartment("Computer Science");
    employee.setName("Nageswara rao");
    employee.setSalary(30000.00);
    employee.setId(471088);

    ksession.insert(employee);

    ksession.fireAllRules();
 }

Это мой файл правил, 

import com.example.springmicroservice1.ruleClasses.temp.Employee
import com.example.springmicroservice1.ruleClasses.temp.EmployeeCache;


rule "Duplicate account validation"
when

$employee : Employee($id : id);
then
    if(EmployeeCache.getEmployeeDetails().containsKey($id)){
        if(EmployeeCache.getEmployeeDetails().get($id).getDepartment().equalsIgnoreCase($employee.getDepartment()) &&
           EmployeeCache.getEmployeeDetails().get($id).getName().equalsIgnoreCase($employee.getName() )){
            System.out.println("Duplicate data");
        }
    }else {
        Employee employee = new Employee();
        employee.setSalary($employee.getSalary());
        employee.setName($employee.getName());
        employee.setDepartment($employee.getDepartment());
        employee.setId($employee.getId());
        EmployeeCache.setEmployeeDetails($employee.getId(),employee);
    }
 end

Когда я запускаю этот проект, я получаю ошибку ниже,

Я искал в google и stackoverflow, но не нашел точного следа для решения этой проблемы.

Заранее спасибо!
