any() matcher behaviour differs from anyObject() for nulls

[GoogleCodeExporter]

In Mockito 1.7, the new any( Class ) matcher says that it is an alias for
anyObject(), but it is actually an alias for isA(), which is different in
the way it handles null values. anyObject() matches nulls; isA() does not.

I think it's useful to have both, but I would prefer any() to follow
anyObject(), considering the naming convention. And isA() already provides
(IMO) a clearer way to test for non-null values. At a minimum, the Javadoc
description of anyObject() should be corrected if the current behaviour is
to stay, to avoid confusion.

The attached test case demonstrates the problem.

You're right - we'll fix it

Fixed in trunk.
any(T.class) is now an alias to anyObject()

Is there a work around for this? How do we match on a null while not returning 
an Object?

You match for null just using null keyword. You match not-nulls using notNull()
matcher (or something similar, don't remember now).

Thanks For the response. 
I can't do that in my situation as it's a two parameter function call, the 
first I want to use anyInt and the 
second I want to use null. But you can't mix matched with value. Null being the 
value.

To demonstrate, I think this works:
        when( mockProfileManager.getProfileByPersonIdAndNetwork( anyInt(), argThat( new 
ArgumentMatcher<Network>(){

            @Override
            public boolean matches(Object argument) {
                return true;
            }

        } ) ) ).thenReturn( profile );

Try isNull() matcher or simply eq(null) :)

Yeah I thought so - I tried that as well before I posted here.
isNull gives The method getProfileByPersonIdAndNetwork(int, Network) in the 
type ProfileManagerImpl is not 
applicable for the arguments (int, Object)  NavigationPanelTest.java    invite-
commons/src/test/java/com/componence/invite/panelTests  line 112    Java Problem
eq(null) also gives the same error.
