java.lang.NullPointerException: anyObject() must not be null

[ChameleonTartu]

I am working with Kotlin, and this NullPointerException creates a lot of headaches.

The return value is non-nullable based on my research around the anyObject() functionality. I propose adding a method anyObjectOrNull() similar to Mockito.anyOrNull() from the mockito-kotlin extension.

Below is a reproduction of this issue:

Is there anything possible to do? I can potentially contribute to this issue as it will significantly help me in my apps.

fwiw, we implemented a number of probably-leaky-abstractions/hacks around this here: https://github.com/trib3/leakycauldron/blob/main/testing/src/main/kotlin/com/trib3/testing/LeakyMock.kt

@henri-tremblay possibly a separate issue, but also recently noticed that the NPE leaves easymock in a bad state. eg, in https://github.com/trib3/leakycauldron/blob/main/testing/src/test/kotlin/com/trib3/testing/LeakyMockTest.kt#L148-L156 , if this test runs BEFORE other tests, it messes them up and they fail with something like IllegalState 1 matchers expected, 3 recorded., I'm assuming because the mock methods don't get called and close off the matcher invocation?
