我正在使用PowerMockEasyMock 1.5.5和EasyMock 3.2。我想模拟在需要@PrepareForTest的方法中创建的新对象。但每当我这样做时，我都会遇到这个例外：

我甚至试图用PowerMockMockito 1.6.x做到这一点，但仍然遇到了同样的问题。我已经阅读了Stackoverflow中的帖子，但没有得到解决方案。我在网上研究了这一点，并了解到旧版Javassist存在一个问题，即PowerMockMockito和PowerMockEasyMock的依赖关系。我在我的版本集中添加了Javassist 3.20.x但仍然遇到了同样的错误。任何人都知道什么是正确的配置？
