TestNG test methods not discovered if they are private

If a TestNG test method is private:

public class TestClass
{
    @Test
    private void testSomething() { /* ... */ }
}

then TestNG recognises the method as a test method and will run it, but Clover does not recognise it as a test method during the instrumentation phase. This results in all such test methods being run during an optimized test run.

Workaround: Make all such methods public.
