Mockito can only mock visible & non-final classes.

Hey,
Looks like some bug with cglib or on the junction between cglib and mockito.
Feel free to contribute a fix :)

I have the same issue with an interface I am trying to mock. Using JDK7
though -- I wonder if that is the problem.

The issue is resolved. thats a simple mistake from my side.
After I changed from Matchers.<Integer>anyObject to Matchers.anyInt(), the
exception disappeared.

Unfortunately the issue I am having is not that simple (as far as I can
tell!), but so far I cannot reproduce it in a simple test case.

@rocketraman When you can reproduce it could you fill a new issue?
@venkynary This might be the junction with Powermock too. As the runner in
PowerMock instantiate the test in their own classloader.
