    org.mockito.exceptions.misusing.InvalidUseOfMatchersException: 
    Misplaced or misused argument matcher detected here:
    -> at org.apache.geode.cache.query.internal.types.TypeUtilsJUnitTest.lambda$booleanCompareShouldThrowExceptionIfValuesAreNotInstancesOfBoolean$7(TypeUtilsJUnitTest.java:441)
    -> at org.apache.geode.cache.query.internal.types.TypeUtilsJUnitTest.lambda$booleanCompareShouldThrowExceptionIfValuesAreNotInstancesOfBoolean$8(TypeUtilsJUnitTest.java:444)

    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.
