OSGI 中使用 Mockito 2 的 ClassNotFoundException

Question

当我尝试运行使用 Mockito 2（版本 2.0.54 beta）在 eclipse 中测试 junit 插件时，调用 org.mockito.Mockito.mock(Class<T>, MockSettings) 上面的堆栈跟踪失败。

我通过这样做设法解决了这个问题

ClassLoader loader = Tread.currentThread().getContextClassLoader();
Thread.currentThread().setContextClassLoader(Mockito.class.getClassLoader());
try {
  org.mockito.Mockito.mock(Class<T>, MockSettings);
} finally {
Thread.currentThread().setContextClassLoader(loader)
}

这似乎不对，需要大量工作才能从 mockito 1 转移到 mockito 2，有没有其他方法可以在 osgi 环境中使用 mockito？
