Issue with Powermockito verifystatic

I have a legacy class which has a static void method which i need to test:

public class A {

    public static void renameTo()
    {
        String ext = "." + this.fileName + ".backup";
        for (File file : getCSVFile()) {
            f.renameTo(new File(file.getAbsolutePath() + ext));
        }

    public static File[] getAllFiles()
    {
        //logic to read the CSV files from the class path
    }


}

Now I have written a test case for it using PowerMockito which looks like this. Now the issue is, even though the renameTo() is called only, if i call PowerMockito.verifyStatic( Mockito.times(10)) the test still passes 

@RunWith(PowerMockRunner.class)
@PrepareForTest(A.class)
@PowerMockIgnore("javax.management.*")
public class ATest {

    @Test
    public void testRenameTo() throws Exception {
        PowerMockito.mockStatic(A.class);
        A.renameTo();
        PowerMockito.verifyStatic( Mockito.times(1));
        //PowerMockito.verifyStatic( Mockito.times(5));//Passes even though the mehod is called only once    
        //PowerMockito.verifyStatic( Mockito.times(10);//Passes even though the mehod is called only once    
    } 
}

Could someone please shed some light into this issue? what I may be doing wrong?

As per the documentation, after the test verifyStatic needs to be called first, then call A.renameTo() to tell it which static method to verify. Example:

// run test
A.renameTo();

// verify interaction
PowerMockito.verifyStatic(A.class, Mockito.times(1));
A.renameTo();
