Wrong test is run when re-running failed DataProvider tests a second time

public class DataProviderExample {

    @DataProvider(name = "test1")
    public Object[][] createData1() {
        return new Object[][] {
                { "Cedric", new Integer(36) },
                { "Anne", new Integer(37)},
        };
    }

    //This test method declares that its data should be supplied by the Data Provider named "test1"
    @Test(dataProvider = "test1")
    public void verifyData1(String n1, Integer n2) {
        boolean pass = n1.equals("Cedric");
        System.out.println(n1 + " == Cedric - " + pass);
        Assert.assertTrue(pass);
    }

}

Running the above test results in the following output:

Cedric == Cedric - true
Anne == Cedric - false

===============================================
DataProvider Example Suite
Total tests run: 2, Failures: 1, Skips: 0
===============================================

Running the resulting testng-failed.xml creates the following output:

Anne == Cedric - false

===============================================
Failed suite [DataProvider Example Suite]
Total tests run: 1, Failures: 1, Skips: 0
===============================================

Running the testng-failed.xml created after the previous re-run-failed creates the following output:

Cedric == Cedric - true

===============================================
Failed suite [Failed suite [DataProvider Example Suite]]
Total tests run: 1, Failures: 0, Skips: 0
===============================================

Expected Result:

Second re-run-failed attempts to re-run the test that has been failing (i.e. invocation-number 1, which was added to the testng-failed.xml file after the very first test run), rather than the test that passed in the very first run e.g. resulting in the following output:

Anne == Cedric - false

===============================================
Failed suite [Failed suite [DataProvider Example Suite]]
Total tests run: 1, Failures: 1, Skips: 0
===============================================

The result is strange:

Cedric == Cedric - true

===============================================
DataProvider Example Suite
Total tests run: 1, Failures: 1, Skips: 0
===============================================

How it is possible to have 1 failure?

Nice catch, thanks!

I close this one as duplicate and will continue to follow the other one.
