Incorrect test with ClassCastException for a function with generics in signature

[EgorkaKulikov]

Description

Download the project https://github.com/SalithaUCSC/spring-boot-testing

Try to generate tests for OrderService.createOrder method with default settings.

Expected behavior

One test for this method containing one line is generated.

Actual behavior

There is a second erroneous test

@Test
    @DisplayName("createOrder: return orderRepository.save(order) : True -> ThrowClassCastException")
    public void testCreateOrder_OrderRepositorySave_1() {
        byte[] byteArray = {};
        // Order save(Order entity);
        (when(orderRepositoryMock.save(any()))).thenReturn(byteArray);
        
        /* This test fails because method [com.rest.order.services.OrderService.createOrder] produces [java.lang.ClassCastException: class] 
        orderService.createOrder(null);
    }

Additional context

Yuri strongly recommends to refactor Traverser.updateGenericTypeInfo.
