getArrayLength on Object in ClassWithEnumTest parametrized test generation

[sofurihafe]

Description

getArrayLength cannot get array length treating array as a non-array object.

To Reproduce

1. Enable parametrized test generation for samples,
2. Run ClassWithEnumTest.

Actual behavior

Generated not parametrized test looks like this:

public class ClassWithEnumGeneratedTest {
    ///region Test suites for executable org.utbot.examples.enums.ClassWithEnum$StatusEnum.values
    
    ///region
    
    @Test
    public void testValues1() throws ClassNotFoundException  {
        java.lang.Object[] actual = ClassWithEnum.StatusEnum.values();
        
        java.lang.Object[] expected = createArray("org.utbot.examples.enums.ClassWithEnum$StatusEnum", 2);
        ClassWithEnum.StatusEnum statusEnum = ClassWithEnum.StatusEnum.READY;
        expected[0] = ((Object) statusEnum);
        ClassWithEnum.StatusEnum statusEnum1 = ClassWithEnum.StatusEnum.ERROR;
        expected[1] = ((Object) statusEnum1);
        
        int expectedSize = expected.length;
        assertEquals(expectedSize, actual.length);
        assertTrue(deepEquals(expected, actual));
    }
    ///endregion
    
    ///endregion
    
    ///region Data providers and utils methods
    
    <...>

    ///endregion
}

Generated parametrized test looks like this:

public class ClassWithEnumGeneratedTest {

        if (expectedResult == null) {
            assertNull(actual);
        } else {
            
            int expectedResultSize = getArrayLength(expectedResult);
            assertEquals(expectedResultSize, actual.length);
            assertTrue(deepEquals(expectedResult, actual));
        }

            statusEnumArray[0] = ((Object) statusEnum);
            ClassWithEnum.StatusEnum statusEnum1 = ClassWithEnum.StatusEnum.ERROR;
            statusEnumArray[1] = ((Object) statusEnum1);
