Hello everyone. I have some issues while trying to use Mockito.spy method on an open class (open class MenuListModel : LinkedList<MenuItemModel>()) in my Robolectric test (not sure if it’s relevant). I’m using org.mockito:mockito-core:2.2.15 and org.robolectric:robolectric:3.1.4 and I get this when running this test

org.mockito.exceptions.base.MockitoException: 
Mockito cannot mock this class: class com.agens.android.vgsnarvei.entities.proxies.MenuListModel.

Mockito can only mock non-private & non-final classes.
If you're not sure why you're getting this error, please report to the mailing list.

Underlying exception : java.lang.IllegalStateException: Error invoking java.lang.ClassLoader#findClass

and some stacktrace below. I tried to use experimental feature of Mockito 2.0 that allows for mocking final classes, but it didn’t work neither (there’s an issue in Robolectric repo about incompatibility of those two)

any idea? Anyone here has an example of working mocking/spying of Kotlin classes with Robolectric?
