A DESCRIPTION OF THE PROBLEM :
The Java compiler fails with a Null Pointer Exception when attempting to use the org.mockito.ArgumentMatchers.eq function to mock a call. Code example:

doReturn(responseEntity)
        .when(restTemplate)
        .exchange(
            anyString(),
            eq(HttpMethod.POST),
            any(HttpEntity.class),
            eq(new ParameterizedTypeReference<>() {}));

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Compilation works, or I am given the correct warning about why the code cannot compile
ACTUAL -
Compilation process errors out

FREQUENCY : always
