接受类及其接口的Java类型(矛盾)

我有一个如下所示的类和接口:

interface Employee {...}

class Developer implements Employee {...}

然后我有实现入职流程中的步骤的类:

interface OnboardingStep<T extends Employee> {
  void perform(T newEmployee);
}

class GeneralOnboardingStep implements OnboardingStep<Employee> {
  GeneralOnboardingStep() {}

  @Override
  void perform(Employee newEmployee) {...}
}

class DeveloperOnboardingStep implements OnboardingStep<Developer> {
  DeveloperOnboardingStep() {}

  @Override
  void perform(Developer newDeveloper) {...}
}

完整的入职流程包括一般入职加上针对开发人员的特定入职.

所以我想做的是:

abstract class OnboardingProcess<T extends Employee> {

  // This is where I need help, see below
  private final List<OnboardingStep<T>> onboardingSteps;

  protected OnboardingProcess(List<OnboardingStep<T>> onboardingSteps) {
    this.onboardingSteps = onboardingSteps;
  }

  public void perform(T newEmployee) {
    for (var onboardingStep: onboardingSteps) {
      onboardingStep.perform(newEmployee);
  }
}

class DeveloperOnboardingProcess extends OnboardingProcess<Developer> {

  DeveloperOnboardingProcess() {
    // This does not work
    super(List.of(
      new GeneralOnboardingStep(),
      new DeveloperOnboardingStep()
    ));
  }
}

这不起作用，因为DeveloperOnboardingProcess中的列表可能只包含OnboardingStep<Developer>，而不是OnboardingStep<Employee>.

但它应该是可行的，因为Developer实现了Employee.(我说的"应该奏效"的意思是:"我希望它奏效了").

我如何调整抽象类中的列表类型，使其也接受接口的加载步骤？
