You cannot use argument matchers outside of verification or stubbing.
Examples of correct usage of argument matchers:
when(mock.get(anyInt())).thenReturn(null);
doThrow(new RuntimeException()).when(mock).someVoidMethod(anyObject());
verify(mock).someMethod(contains("foo"))
This message may appear after an NullPointerException if the last matcher
is returning an object
like any() but the stubbed method signature expect a primitive argument, in
this case,
use primitive alternatives.
when(mock.get(any())); // bad use, will raise NPE
when(mock.get(anyInt())); // correct usage use
Also, this error might show up because you use argument matchers with
methods that cannot be mocked.
Following methods *cannot* be stubbed/verified:
final/private/equals()/hashCode().
Mocking methods declared on non-public parent classes is not supported.
