Thread Weaver 调用TargetException

如何解决Thread Weaver 调用TargetException

我正在尝试让 Thread weaver 工作，但无论我尝试什么，我总是遇到下面的异常。

我创建了一个干净的项目，其中只有 EasyMock、JUnit 和 Thread weaver，代码是 Thread weaver 文档中的示例（我使用的是 EasyMock 4.2，我在 JDK 15、JDK 9 和 JUnit 4 上进行了尝试）和 JUnit 5）。

有没有人知道...？

测试类：

import java.util.ArrayList;

public class MyList extends ArrayList {
    synchronized public boolean  putIfAbsent(Object o) {
        boolean absent = !super.contains(o);
        if (absent) {
            super.add(o);
        }
        return absent;
    }
}

测试：

import com.google.testing.threadtester.*;
import org.junit.Test;

import static org.junit.Assert.assertEquals;

public class MyListTest  {

    private MyList list;

    @Test
    public void testThreading() {
        AnnotatedTestRunner runner = new AnnotatedTestRunner();
        // Run all weaver tests in this class,using MyList as the Class Under Test.
        runner.runTests(this.getClass(),MyList.class);
    }

    @ThreadedBefore
    public void before() {
        list = new MyList();
    }

    @ThreadedMain
    public void mainThread() {
        list.putIfAbsent("A");
    }

    @ThreadedSecondary
    public void secondThread() {
        list.putIfAbsent("A");
    }

    @ThreadedAfter
    public void after() {
        assertEquals(1,list.size());
    }
}

例外：

编辑：

澄清 - 库在那里并且项目编译。错误仅在我实际运行测试时发生
