why spied object call real method?

[GoogleCodeExporter]

What steps will reproduce the problem?
    @Test
    public void spyTestOne() {
        Jack spyJack = spy(new Jack());
        when(spyJack.go()).thenReturn(1111);

        assertEquals(1111, (spyJack.go()));
    }

    class Jack {
        public int go() {
            System.out.println("I say go go go!!");
            return 0;
        }
    }

What is the expected output? What do you see instead?
the test has passed, but console print "I say go go go!!"
i think go() will do nothing, isn't it?

What version of the product are you using? On what operating system?
mockito 1.9RC 
win7 32bit

Please provide any additional information below.

i got it.

i should use 

doReturn(1111).when(spyJack).go();
  >>> instead of
when(spyJack.go()).thenReturn(1111);

but i think it's a trap, right?

Hi,

Exactly! But I'm afraid we cannot do much about it.
However this is documented in the Javadoc. But we made it more explicit for the 
next release on other javadoc places as well.

Hope that helps
