mockito - "any" and "isA" matchers

The most obvious interpretation of any() matcher in mockito is that it accepts any object. Ok - and what about any(Clazz.class)? It accepts any object of class Clazz.

Actually those two sentences contain fallacies… First: any accepts also null parameters (it doesn’t require the argument to actually exist!). Secondly: any(Clazz.class) accepts any object of … any class! Actually, in most cases it would be probably better to use a isA matcher - which simply checks the class of passed object (the object needs to exist in the first place!).
