升级了mockito，现在在Mockito.spy上获得了java.lang.ClassCastException

Question

我刚刚升级到Mockito v 1.10.18（使用JUnit 4.12和PowerMock 1.6.2）。过去常常工作......

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:test-context.xml" })
@DirtiesContext(classMode = ClassMode.AFTER_CLASS)
@FixMethodOrder(MethodSorters.NAME_ASCENDING)
@PrepareForTest( Transport.class )
public class AccessCodeServiceIT 
{

    @Rule
    public PowerMockRule rule = new PowerMockRule();

    …

    @Autowired
    private EmailService m_emailSvc;

    @Before
    public final void setup()
    {
        final EmailService emailSvcSpy = (EmailService) Mockito.spy(getTargetObject(m_emailSvc));

但现在使用Mockito的新版本，我在上面的行中得到以下异常......

findAccessCodeByCode(org.mainco.subco.ecom.service.AccessCodeServiceIT)  Time elapsed: 1.588 sec  <<< ERROR!
java.lang.ClassCastException: org.mainco.subco.email.service.EmailServiceImpl cannot be cast to java.lang.Class
