code: public static <K, V> Map<K, V> anyMap() {
          reportMatcher(new InstanceOf(Map.class, "<any map>"));
          return new HashMap<K, V>(0);
      }
docs: Any <strong>non-null</strong> <code>Map</code>.
  
  <p>
  Since Mockito 2.1.0, only allow non-null <code>Map</code>.
  As this is a nullable reference, the suggested API to <strong>match</strong> <code>null</code> wrapper
  would be {@link #isNull()}. We felt this change would make tests harness much safer that it was with Mockito
  1.x.

  See examples in javadoc for {@link ArgumentMatchers} class.
