PowerMockRunner вызывает ExceptionInInitializerError при запуске тривиального теста

Question

Я не могу запустить очень простой тестовый класс с помощью тестового runnner Powermock. Это вызывает ExceptionInInitializerError. Это похоже на проблему с зависимостями от пути к классам, однако я пробовал несколько вариантов версий зависимостей, но все они вызывают одну и ту же ошибку. Как я могу пройти этот простой тест при использовании тестового бегуна Powermock?

Тест Код:

package net.solasistim.hello; 

import org.junit.Test; 
import org.junit.Assert; 
import org.junit.runner.RunWith; 
import org.powermock.modules.junit4.PowerMockRunner; 

@RunWith(PowerMockRunner.class) 
public class HelloTest { 
    @Test 
    public void testMain() { 
     Assert.assertTrue(true); 
    } 
} 

POM проекта:

<project> 
    <modelVersion>4.0.0</modelVersion> 
    <groupId>net.solasistim.hello</groupId> 
    <artifactId>hello</artifactId> 
    <version>1</version>

Запуск mvn clean compile test вызывает следующий вывод:

PowerMock и новейший CGLIB, кажется, не ладить с друг друга. Я не могу сказать вам точно причину, но если вы понижена с 3.0 до 2.2.2, он должен работать:

<dependency> 
    <groupId>cglib</groupId> 
    <artifactId>cglib</artifactId> 
    <version>2.2.2</version> 
    <scope>test</scope> 
</dependency>
