GroovyCastException：无法将类为[另一个晦涩的闭包]的对象[某些晦涩的闭包]强制转换为[您的业务接口/类]

Question

我有一个松耦合的代码结构，可用来为Katalon Studio测试提供动力。它由一个TaskInfo个List个PayRateInterface组成。另外，TaskInfo将来会实现TaskInterface（因为将有一个具有TaskInterface的类）。

在此方法的第一行中，TaskInfo：

@Override
public PayRateInterface getMostRecentPayRate() {
    PayRateInterface newestPayrate = payRates.get(0);
    for (PayRateInterface payRate : payRates) {
        if (payRate.getTimestamp().after(newestPayrate.getTimestamp())) {
            newestPayrate = payRate;
        }
    }
    return newestPayrate;
}

，我得到运行时异常：

Test Cases/AddInvalidTasks FAILED because (of) org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'Script1530218543089$_run_closure1@1358b28e' with class 'Script1530218543089$_run_closure1' to class 'com.ezsoftpos.beans.employee.tasks_and_rates.PayRateInterface'

PayRateInterface的定义如下：

public interface PayRateInterface {
    double getPayRate();
    Date getTimestamp();
}

其余的类和接口定义如下：

用例

我想说

TaskInfo noName = new TaskInfo('', Arrays.asList({ 
        new PayRateInfo(15.00)
    }))

然后就像

noName.getMostRecentPayRate()

如果有的话，我在做错什么吗？
