Integration PowerMock and testNG Issues

[GoogleCodeExporter]

What steps will reproduce the problem?
1.created a object factory in the testNG.xml file 
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name = "EmpappSuite" verbose = "1" 
        object-factory="org.powermock.modules.testng.PowerMockObjectFactory">
  <test name = "daos">
     <classes>
         <class name = "com.DAOTest"/>
     </classes>
  </test>
</suite>
2.and had a test class with a dataprovider

@PrepareForTest(DBUtil.class)
public class DAOTest {

    private EmpDAO empDAO;

    @Mock
    private CallableStatement cs;

    @Mock
    private DBUtil dbUtil;

    @BeforeMethod
    public void setUp() throws Exception {
        empDAO= new EmpDAO();
        MockitoAnnotations.initMocks(this);
    }

    /* Custom one time tearDown() implementation after test method. */
    @AfterMethod
    public void tearDownAfterTest() throws Exception {
        empDAO = null;
        cs = null;
    }

    @Test(dataProviderClass = EmpDaoDataProvider.class,
            dataProvider = "empDaorequest")
    public void testCheckoutStatus(
            CheckoutStatusRequest request) throws Exception {
        Assert.assertNotNull(request);  
        some testmethod which will take the reqest
    }
}
3.

What is the expected output? What do you see instead?
 when i run the testNG suite i am getting the following error

java.lang.RuntimeException: Can't invoke method public void
com.DAOTest.testCheckoutStatus(the method name in that) throws
java.lang.Exception on this instance of class com.DAOTest_$$_javassist_0

Are you using TestNG 5.11? Could you provide the class you're trying to test as 
well?

Won't fix due to no response from user.

I see the same error. 
The only difference is that I don't use a dataProvider.
@ObjectFactory
    public IObjectFactory getObjectFactory() {
        return new org.powermock.modules.testng.PowerMockObjectFactory();

    }
Just these lines produce a class mismatch error. 
I am using TestNG  5.13.1

Unfortunately PowerMock doesn't support DataProviders with TestNG. It would be 
very much appreciated if you could provide a patch.

I did not use a dataprovider. The problem got resolved when I updated my 
powermock version to 1.4.10

Thanks!

I have the same error using PowerMock and TestNG DataProviders. It would be 
really great if you could provide a patch for this issue.
I am using TestNG 6.3.1 and powermock 1.4.11.

Regards
